Unsure if I installed my H100i correctly, is this a normal CPU temp under load?

Episodic · Aug 5, 2014

I added my own thermal paste to the CPU, and I'm not sure if it spread out evenly enough. This is running Prime95, is this a good temperature to have, also is there any way I could lower it even more?

ASUS Z97-A
i7 4770k
Corsair H100i

it needs to be about 60 to 70 c see this for more detail

i hope this clears it for you

You dont spread thermal paste anymore you are supposed to put a small dab abt the size of a grain of rice in the center and let the cooler spread it. That said those temps are okay. but they could defiantly be cooler.

60c at stock clocks on with a h100i? No, I'd reapply your thermal paste.

Dunlop0078 :

I did just put a dab on it and let it spread out. First time I did it, I checked after I put the H100i down and it turned into a small circle in the center of the CPU. Then I wiped it off and put a little more on, haven't checked to see how it spread out, but is it suppose to cover the whole CPU?

mouse24 :

I'll reapply it then and post the new temperatures.

Episodic :

You dont need much at all you are better off with less than enough than more than enough and the paste doesnt need to cover the whole cpu just the cores in the middle.

It ended up making it worse!

Pre-heat sink:

After heat-sink:

Idle:

Load:

Why did my clock speed drop dramatically here as well^?

mouse24 · Aug 6, 2014

Ouch, did you use more or less than the amount above? Use a bit more than that, id say maybe a bit less than double that amount (rough estimate).

Redo that like right now. Legitimately right now. Its clocks are low because its throttling down to stop it from dieing.

Just out of curiosity what paste is that? It looks really thick.

RobCrezz · Aug 6, 2014

As per your other thread, you didnt apply enough, the coverage of the heatspreader is poor.

Also, what paste is that? as mouse says, looks much too thick.

Dunlop0078 · Aug 6, 2014

I think the paste is your problem that stuff looks very poor quality i have never seen paste spread like that a dab like that of my noctua nt h1 would have nearly covered that.

It's arctic silver 5,should I order something else?

RobCrezz · Aug 6, 2014

Episodic :

Try arctic MX-4, much thinner and easyer to apply. Noctua NT H1 is also very good.

Dunlop0078 · Aug 6, 2014

Episodic :

I have some arctic silver 5 and it always seemed to spread better than that. turning it and giving the paste heat will help it spread too.

Dunlop0078 · Aug 6, 2014

RobCrezz :

I have never tried the mx-4 but i have heard good things. And i believe nt h1 and mx4 are non metallic as well unlike AS 5 so you dont run the risk of shorting anything if some drips on your mobo.

Dunlop0078 · Aug 6, 2014

And the cpu will drop to 2.0ghz or less all the time at idle its supposed to, to save energy and what not.

RobCrezz · Aug 6, 2014

Yeah Mx-4 is decent enough, and pretty cheap. Not quite as good as NT H1 or Phanteks TH-NDC, but close enough.

RobCrezz · Aug 6, 2014

I see no reason to use AS5 any more, when theres ones like MX-4 that dont have to have heat cycles to cure or anything.

Unsure if I installed my H100i correctly, is this a normal CPU temp under load?
