One myth down.. more to come..

Can you get higher temps with too much paste?

ive been running my test rig for 3 days now testing somthing. more on that later...

this is how much i have used

for the test.. 

plz send a cleaning crew

 

on to the results (tests has been ran 3 times each)

What 450W CPU could you cool with an AiO? Where are you measuring the system power draw? The entire PC can't draw less than the CPU.

But to answer that question, no you can't screw up your temps by using too much paste. I'm writing this for everyone, not just you specifically. As long as enough mounting pressure gets applied, the excess will just squish out, leaving the minimum needed in between CPU and cooler

this was an typing error into excel. ty for pointing it out  

corrected now

what randoms are we talking about?  

[freeagent]

So we started talking about this the other day and you are now 3 days into testing? Ok.

im testing somthing that you have not been a apart off. 

[8tg]

I mean technically you don’t even need a cpu cooler

just a fan is good enough

@freeagent

 

Did you use less pressure to ensure that the paste was thicker?  If not, that is why the results are essentially the same.

He's testing something to verify what I did with my Notte.

huh   i always tighten the coolers all the way down, the same way

Then your test results do not demonstrate the results you'd get from a thicker layer of paste since the pressure pushed most of it out...

if i tighten in a different way, that variable alone is bigger than  too much paste vs normal paste

and normal tighten cooler will squeeze out the paste making the layer normal

You set out to prove or disprove the "myth" that @freeagent stated. What are you going to do?

How much thermal paste you displace then has no impact on the thickness between the cooler and CPU.

If this drama was based on the idea that too much paste can cause problems, then @NorKris's testing isn't setup properly to demonstrate that, as you suggest.

 

The latter testing would involve some sort of spacer that would increase the distance between the cooler and IHS that would allow for an extra 0.1mm or so of thermal paste between the two surfaces. That would involve actual testing though and simply not just wasting thermal paste.

 

Like using 2 gallons to demonstrate that a 1 gallon will get filled an overflowing it by 1 gallon.

true cuz the answer would be: so much that it flows into contacts points in  the ram and pcie slot...

Well, a quantity above the minimum really has no impact on the contact between the IHS and cooler simply because tightening down the cooler displaces what doesn't fill the space, which is a relatively fixed quantity.

 

Sure, putting that much might cause problems with other things, but it won't affect cooling of the CPU as long as the cooler can still be tightened to the same depth. That's where properly testing this would involve adding some sort of spacer of an even thickness, like 0.1mm or 0.2mm, so that there's that much extra thermal paste between the cooler and IHS.

aah now i understand, 100% agree. 

i predict that with spacers   the "too much" is better than "too little"

You really want no space between a heat sink and heat source, thermal paste being designed to fill in air gaps between them since no two surfaces are perfectly mated together. Thermal paste doing a lot better than air at transferring thermal energy.

 

Unless you use so much mounting pressure that you pressure weld them together  No thermal paste needed then.

I'm glad you finally understand, Kris. So, will you proceed to test with a thicker layer produced by a gasket to hold it in place and keep the distance larger than what happens when you tighten it down without a gasket?

why would i test a if cpu temps increase if u dont tighten the cooler? thats a ting every1 understand will happen????

[Ralfi]

Funny responses . But appreciated @NorKris OP 

 

I took the experiment in another way - to use much more paste to make sure you covered the whole contact point consistently (compared to using too little & maybe not covering it all with a consistent squished layer), as opposed to having a thicker layer of paste.

The point that was made by @freeagent is if the TIM is thick enough between the 2 surfaces, it will act as an insulator. I've seen this mentioned many times here and elsewhere. Personally, I think some materials are prone to be more insulative than others. 

 

It really boils down to resistance to transfer. The thickness of a material affects the conductivity of any firm of energy, as do other factors such as molecular density. In electrical systems, the thinner the gauge, the greater the resistance. The closer the 2 contact surfaces are, the greater the thermal conductivity is.

You just said you finally understand what @Agallexplained. That is what is needed. Put the gasket in to maintain thicker layer of TIM and then tighten it fully.
