Is Thermal Paste Necessary For Cpu

EucleX · Jul 21, 2014 136 0 4,690 2

I am going to upgrade my CPU and I was wondering if I am going to demand thermal paste for the fan. It'due south an Athlon X4 750k.

I really don't think this is what the OP was asking.
I tin see the need though to right some of the misinformation.

EucleX, your new CPU will come with a CPU cooler included.
This cooler will have a foursquare of heat transfer material on the base.
If you are using this libation, yous do not need any other thermal paste.
This is different to the discussion in a higher place about non using any estrus transfer textile at all, which would be unwise.
If yous accept purchased an after market CPU cooler, this will come with thermal paste that must be applied.

If your asking, practice you need Whatsoever thermal paste at all when placing the fan on the cpu... yes you do.

most cpu fans come with "pre-applied" paste... that stuff is crap, but if your just basic computing it is fine

MeteorsRaining · Jul 27, 2014 8,346 iii 38,965 1,977

Yep its necessary, the heatsink usually comes with paste, but for the question, its very much necessary to apply paste for effective dissisipaiton of estrus.

Darkbreeze · Jun 24, 2014 72,064 5,316 167,690 9,139

Yes. Thermal paste should always be used when installing or reinstalling a cpu. The old paste needs to be cleaned off the CPU and fan heatsink and a rice sized amount of thermal paste should exist applied to the center of the cpu prior to installation. Use a lint gratuitous cloth or java filter with rubbing alcohol to clean the one-time paste off. There are plenty of tutorials on how to do it if you google it. Don't use a pea sized amount of paste, it's too much paste for newer cpus with smaller physical sizes. The type of thermal paste isn't that important for your usage as long equally it's a mainstream make.

saint19 · Mar 20, 2009 xv,733 xvi 57,965 1,147

Off course that is necessary. Why?

Because the thermal paste is what makes possible the heat transfer between your CPU and cooler.

Darkbreeze · Jun 24, 2014 72,064 v,316 167,690 9,139

If your asking, do y'all need ANY thermal paste at all when placing the fan on the cpu... yes you exercise.

most cpu fans come with reapplied paste... that stuff is crap, but if your just basic computing it is fine

I think you meant "pre-applied", non "re-applied". Heh. Simply and so as not to misfile.

VincentP · Oct 18, 2013 4,105 1 26,965 958

The stock CPU cooler will come with a thermal pad on the lesser of the heatsink.
This is perfectly fine for utilize with the stock cooler.
There is no reason to use thermal paste with this libation and if you did want to, you lot would first have to clean off the thermal pad.

If yous take bought an after market CPU cooler, this probable comes with thermal paste.
In this case, the paste must exist used.

Dazinek · Sep 9, 2014 541 0 11,160 92

If your asking, practice you need Whatsoever thermal paste at all when placing the fan on the cpu... yes you lot practise.

nigh cpu fans come up with reapplied paste... that stuff is crap, just if your merely bones calculating it is fine

I think you meant "pre-applied", not "re-applied". Heh. Just so equally not to confuse.

Ooops.. typed that wrong, I meant pre-applied lol

i remember the correct answer is no, it isn't. But highly highly recommended. Put it on and so cheque your temps, they will be alot higher, but i would guess nevertheless well within safe temps. Metal to metal transfers heat simply fine, but there are tiny bumps on the surface, the paste fills these in. Notwithstanding if u exercise what i said, its at your own risk. That being said, most if not all mod equipment has temp sensors that volition shut themselves downward when they get to hot, so in my opinion, not much take chances.

Darkbreeze · Jun 24, 2014 72,064 v,316 167,690 ix,139

i think the correct respond is no, it isn't. Merely highly highly recommended. Put it on and so check your temps, they will be alot higher, but i would guess nevertheless well inside safe temps. Metallic to metal transfers estrus just fine, but in that location are tiny bumps on the surface, the paste fills these in. However if u exercise what i said, its at your own hazard. That existence said, most if non all mod equipment has temp sensors that will close themselves down when they get to hot, so in my opinion, non much hazard.

And you're a fool if you think thermal paste, even if it's only mayonnaise, isn't necessary. And not that anybody is going to listen to that nonsense anyhow, but it'south pretty irresponsible to try to pass the idea that it IS ok, on to somebody who might actually take you lot seriously. If you actually believe that nonsense, yous need to offset over from scratch and do your inquiry. If it WASN'T necessary, we wouldn't even exist having this conversation. I approximate in a sense you're right, but by that way of thinking, information technology isn't actually necessary to put oil in your car either. Oh, it will run without it, for a while. And it will shut downwards when it gets besides hot too. Unfortunately, it tends to cause irreparable damage, just like repeatedly overheating a cpu to the bespeak of thermal shut down does. You should exist more cautious with your advice, lest yous cause some inexperienced novice who isn't going to pay any attention to their thermal readings on whatsoever regular basis, to take you serious.

EucleX · Jul 21, 2014 136 0 iv,690 ii

Well, I was at Fry'south watching a guy build my PC and I didn't see him apply whatever thermal paste onto the processor? He simply put on the estrus sink and nailed it down. Information technology was an A4 5300.

EucleX · Jul 21, 2014 136 0 four,690 2

Yes. Thermal paste should always be used when installing or reinstalling a cpu. The old paste needs to be cleaned off the CPU and fan heatsink and a rice sized amount of thermal paste should be applied to the centre of the cpu prior to installation. Employ a lint free fabric or java filter with rubbing alcohol to clean the erstwhile paste off. There are enough of tutorials on how to do information technology if y'all google it. Don't use a pea sized corporeality of paste, it'south also much paste for newer cpus with smaller physical sizes. The type of thermal paste isn't that important for your usage as long as information technology's a mainstream make.

I am going to swap out my CPU. What if my CPU doesn't come with thermal paste?

VincentP · Oct 18, 2013 4,105 one 26,965 958

As I wrote earlier, stock CPU coolers do not come with thermal paste.
Instead, they have a thermal pad already attached to the base of the heatsink.
This pad does the same chore as thermal paste only it is much more fool proof when installing.
Quality thermal paste may be a better conductor, merely you only bother with this if also using a quality CPU cooler.
Unless over clocking, the stock cooler and the included thermal pad are fine.

epson · Apr 6, 2009 14 0 eighteen,510 0

i call up the right answer is no, it isn't. Simply highly highly recommended. Put it on and and then check your temps, they will be alot higher, but i would approximate still well within safe temps. Metal to metallic transfers heat just fine, but there are tiny bumps on the surface, the paste fills these in. Yet if u practice what i said, its at your ain risk. That being said, about if non all modern equipment has temp sensors that volition shut themselves down when they get to hot, so in my opinion, non much risk.

And you're a fool if y'all recollect thermal paste, fifty-fifty if it's just mayonnaise, isn't necessary. And not that anybody is going to listen to that nonsense anyhow, simply it's pretty irresponsible to try to pass the idea that it IS ok, on to somebody who might actually have you seriously. If you lot actually believe that nonsense, you need to beginning over from scratch and exercise your research. If it WASN'T necessary, we wouldn't even be having this conversation. I guess in a sense you're correct, but by that fashion of thinking, it isn't really necessary to put oil in your car either. Oh, it will run without it, for a while. And it will shut downwardly when it gets also hot too. Unfortunately, it tends to cause irreparable harm, just like repeatedly overheating a cpu to the indicate of thermal shut downwards does. You should be more cautious with your advice, lest you crusade some inexperienced novice who isn't going to pay any attention to their thermal readings on any regular footing, to take you serious.

i was very cautious with my advice, i gave plenty of warnings. But y'all besides have evidently never put a heatsink on without thermal paste earlier and monitored what happened. In my first hand experience, nothing bad happened, always. maybe i was lucky, or perhaps your just passing on advertizement that thermal paste companys have shoved downwards our throats for years. Paste is designed to HELP transfer heat, and btw there are alot of cases where thermal paste HARMS the transfer of oestrus, aka desperately practical, old, generic make that insulates instead of transfering rut, ect ect. Until u, yourself, really does it, u shouldn't comment. Its smart to use thermal paste certain, it will lower your heat sure, but u do realize what modern cpu's and gpu'south are rated to withstand heat wise right? my "guess" is the simply way u would maybe reach those temps without thermal paste is if y'all're using the stock coolers.

Lastly, don't telephone call people fools. This is a fence, no need for personal attacks, sometimes being wrong or misinformed is hard to bargain with merely try to take information technology as a learning experience.

I would say apart from epson, anybody else Toms will tell y'all that yes, yous practise need to use thermal paste, or a thermal pad. It would exist pretty unwise to not employ it, every bit stated your CPU will heat up to the bespeak of shutting down to prevent damage. This is a prissy characteristic, but non meant for regular employ, as the repeated overheating of the CPU will eventually lead to total failure, and if the sensor fails to shut it down in time information technology could get expensive to replace everything that dies. You lot should spend the $five-10 for a tube of decent paste and save yourself the headaches.

EucleX - There is a high likelyhood if they strapped the cooler to the CPU without applying paste, it probably had a pad on it. Was it a factory cooler that came with the CPU or an aftermarket ane.

Thermal paste is ABSOLUTELY necessary for a CPU-heatsink application, no questions about it, in that location are lots of reviews that will dorsum that up, i tend to reference the hardware secrets review where they saw no thermal paste hitting 62C, any thermal material(excluding chocolate) topped out at 43C
http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-Feb-2012/1490/five

Now, you are correct that metallic to metal transfers rut ameliorate than thermal paste, which is why heat pipes are soldered to their base of operations considering the metal conducts oestrus far better than whatsoever not-metallic interface would, HOWEVER when y'all take 2 surfaces that were not designed together y'all get worse results without thermal paste, the top of your CPU tends to exist slightly curved, the base of the CPU cooler has tooling marks from beingness machined, this results in a very pocket-sized actual contact area so while that contact area has amend heat conductivity than information technology would flowing through the TIM, the limited surface area results in greatly increase temperatures.

IF AND But IF the CPU and heatsink were designed side by side to be perfectly coplanar, with no curving or gaps, and were both polished to a very apartment surface would you become meliorate heat transfer past skipping thermal paste, using a non-lapped CPU and not-lapped cooler you should Ever use thermal paste.

Check out frosty tech heatsink reviews to encounter just how rough some of them are, they exercise surface flatness and surface roughness checks at the offset of all their reviews, yous'll notice nil is actually flat....

If yous have purchased an after marketplace CPU libation, this will come with thermal paste that must exist applied.

You definitely need thermal paste for a CPU cooler.

crabbypatties

Information technology would practise more harm then practiced to not use it, so really ask yourself why not?

EucleX · Jul 21, 2014 136 0 iv,690 2

I would say apart from epson, everyone else Toms volition tell you lot that yes, you practise need to use thermal paste, or a thermal pad. It would be pretty unwise to not utilise information technology, as stated your CPU will heat upwardly to the point of shutting downwards to prevent damage. This is a prissy feature, but not meant for regular use, as the repeated overheating of the CPU volition eventually lead to total failure, and if the sensor fails to shut it downward in time information technology could become expensive to supersede everything that dies.

It was a cooler than came with the A4 5300. I think information technology was nigh likely a pad.

Aha thanks man. This is really the answer I was looking for. There was a lot of commotion going on in this simple question xD

i was very cautious with my advice, i gave plenty of warnings. Just you also have obviously never put a heatsink on without thermal paste before and monitored what happened.

Lastly, don't telephone call people fools. This is a contend, no need for personal attacks, sometimes existence wrong or misinformed is hard to deal with simply try to have it as a learning feel.

Ok, I won't call y'all a fool. Come across, I didn't telephone call yous one. And it's not a debate, it'due south a fact. But obviously, Mr. " I've washed it in one case so I know information technology works and you don't considering you lot've never washed it" , I haven't done it because during schooling where I received my A+ certification way back in the early 90'southward, they expressly relayed to us the importance of thermal compound.

Afterwards about 2500 CPU installations I think I'thou qualified to say that indeed, y'all are a fool who is trying to spread foolishness to others. This is not a personal set on, it is simple fact. What is besides apparent, is that you've never seen a thermal protection fail, a faulty sensor neglect to engage the thermal protection, thermal runaway or a organisation without thermal paste that couldn't fifty-fifty run a single instance of a browser window without heating to the point that the thermal protection shut the unit of measurement downward and in doing so made the unit of measurement useless until the processor was properly installed. Of course, past and so thermal impairment will take likely occurred and the CPU may never operate error free again. Or it might. But why would you ever take a chance it over threescore cents worth of paste and one minute of your time?

So, over again, information technology's a bad thought in whatsoever scenario and regardless of opinion. It is what it is.
