Choosing thermal pad

[Spy Boy]

Hey

I heard that thermal pads are superior than paste. But I am struggling with choosing one for my PC. My CPU is i5 8400. I tried to Google but couldn't find the answer...

I just want to add sometime. Beware of C°/W. Higher mean hotter, and lower mean cooler. High C°/W is meant for chip that like hot, and lower C°/W is meant for chip that like cool.

Bottom line, this thermal pad from Thermal Grizzly should be used for a silicone sensitive chip. That is when electrostatic discharge could make silicone worst for some sensitive chip.

As usual you are failing to be helpful or explain how on earth a thermal pad vs paste has anything to do with static electricity.

For the OP.
You can use a program like hwinfo64 or setup afterburner on screen display to show it for you, but, basically, at 95-100c it will throttle itself to stop it from firing, pretty much anything below that is fine, chances are you'll be running in the 50-70c range give or take.

No... I'm being helpful. It is true, we wasn't allowed to use any silicone-based product in ESD safe area. Also, I never talked about thermal paste.

Nope, you only need to change it every ~5 years depending on the thickness of the paste. Paste doesn't actually go bad, it's because the mounting pressure of the CPU cooler that spreads the paste continues to push the paste out off the edges of the IHS over time, so it can thin out a lot if you use a thin and runny paste like Kryonaut.

I had a thin layer of Kryonaut on my CPU and it lasted about 2 years. Thicker pastes like ARCTIC MX-4, Noctua NT-H1, etc. will last closer to 5 years because it takes longer for those pastes to thin out.

Okay. But if Grizly thermal pad will do the same as it was said above, then I probably would go for thermal pad as it easier to install.

It's so easy to re-apply paste that it's even more stupid to use a thermal pad, you're likely going to get worse thermals with a pad, which is why people don't use them on CPUs other than for testing. If someone told you that pads were better than pastes, they have absolutely no idea what they're talking about. Pads do not spread across the IHS and give proper coverage, and they're too thick to provide perfect conductivity.

I wouldn't use a pad unless paste is not possible for any silicone sensitive chip. Unrelated, we wasn't allowed to use silicone based hand moist in ESD safe area, because it could failed me in ESD tester.

none of what you said is at all relevant, which is why i asked what it has to do with the discussion.

also, intersting how you cant use any silicon based product in an esd (safe?) area seeing as you are likely working on silicon based products :P not to mention pretty much none of that has any impact on using thermal paste or an overpriced under-performing thermal pad.

Silcone-based hand moist could failed me at ESD tester. What I stated is relevant to OP.

[Monk]

you should be using gloves in that kind of area really anyway.

also, still irrelevant.

What I said is relevant because I said pad should only be used if the chip is a silicone sensitive. That mean if paste is not possible.

If picked a wrong thermal pad, then it could make CPU ever hotter.

And which consumer 8400's would be 'silicon sensitive'?

Not that I really get how any of them could be really, care to explain? I legitimately don't see how this could be an issue.

Silicone sensitive mean ESD could kill a chip easily. ESD is very radiacted and silicone paste could lead a chip to being charged with ESD. That is probably how I killed my GPU with a silicone paste on the exposed silicon GPU.

If you seeing thermal grizzly's thermal pad, this pad is good for silicone sensitive chip. Which is why I advised against it unless it is a silicone sensitive chip.

Thermal paste is the best but thermal pads are good and when you put thermal pad on your CPU you still can use it when you change your CPU

Well, the thermal paste is cheap btw

This is going on an ihs... So has no chance of static build up, which, even if it did is very hard to kill modern electronics with, if you screwed up your gpu, it was likely that you didn't prepare the gpu properly by protecting the circuitry around the chip and the conductive paste touched said areas shorting it, not just because it was in the vicinity of the chip itself.

Should of treated it like liquid metal, or use a more modern non conductive paste as I'm guessing it was either cheap or arctic silver as those are the only conductive pastes I can think of these days.

So, once more, your point had zero relevance but you have shown that you don't know how to use thermal paste properly...

What I said is relevant to OP's question about thermal pad. And yes, I know how to use both paste or pad. As I said, look at thermal grizzly's thermal pad and you will see that it is for silicone sensitive meant to minimize ESD.

PS you don't know anything about my broken GPU because you were not here with me that time. I used silicone paste at right size and ESD killed it, end of story.

Again, it can't have by itself, like, it's actually all but impossible, silicon by itself won't build up a huge charge and it needs a hell of a charge to kill something, hell ltt did a video recently when they could barely kill stuff while they were actively trying to kill it.

The only way your description of killing a gpu would if happened is the conductive paste squished out and shorted the surrounding components.

Which means, you didn't prepare the pcb properly by protecting said components with a medium, I use clear nail varnish myself, hell, there's even the photos on my artwork profile of how to prep the area around the chip from when I recently direct die mounted my cpu using liquid metal for your future reference.

Once more as op is using a standard 8400 with the ihs in place, there is practically no way to zap it and harm it with thermal paste.

I've no idea why you are so paranoid about esd as it's really not a big risk around the vast majority of electronics for many years now.

That doesn't mean ESD won't killed computer. There is no such as sensitive-free chip in the PC, only in perfect reality (which we are not in it). Even I follow a description before I applied a silicone paste. There is no error in my way.

I was there when ESD killed GPU, power supply, and motherboard/mainboard in rare occasions.

So, talk me through, how paste built up enough of a charge to fry the chip but it definetly wasn't that the conductive paste leaked out causing a short, you know, the most likely event unless you tried to build up a charge.

Killing electronics with static us remarkably hard to do, heck my dad ran a business for 30 years dealing with electronics/circuit boards with 10 engineers repairing stuff with zero esd protection beyond not being a loon and it was maybe 1 dead item every few years at worst. Since then, stuff has become wayyyy better shielded from static, I'm yet to frag anything in 20 years pretty much.

Yet you, putting conductive paste on a gpu dragged it just by being there and not because it caused a short...
