High temps on Corsair H60 with Core 2 Quad (Stock)

Hi there. I have a Corsair H60 cooling an Intel Core 2 Quad Q9300 running at stock 2.5GHz. I performed some tests to compare the stock cooler with the H60 and found to only have a 2 degree difference.

In both cases I was using the thermal compound already applied to the coolers (had the stock on for about 3 years and only just got the H60).

I have 1 120mm fan and I tried both push and pull. The pump speed reads 4470RPM and the fan reads 1400RPM. However the temps are still at 60 degrees idle and 72 degrees load (celsius). I have not yet tried reseating the cooler since my thermal compund is still on it's way but any other ideas why it could go wrong?

Bearing in mind with stock cooler I had the case closed and with H60 I even opened the case and ran it in the open.

Thanks in advance, Huzi

You need to remount the cpu cooler.

Did you clean the processor IHS with isopropyl alcohol and a lint-free cloth/rag/etc. before you mounted the cooler? Is the cooler seated tight enough? Did you screw it in with an cross pattern?

And do not use too much paste.

That's why I got the thermal paste. Hoping it's something as simple as that.

I actually didn't used isopropyl alcohol but I did clean off the crappy old gunk, it looked pretty darn clean, I could see the text on it very clearly. It's definitely tight enough, it doesn't shift about in any direction with considerable force and the backplate was a mofo to get on but is on there really tight now. And I made sure I did cross pattern tightening.

The new thermal compound comes with 99.8% isopropyl and lint free cloths so I don't need to ruin the last one I need for my glasses :p 

Could there be anything else causing it?

If all else fails I may get a pressure optimized 120mm fan and do push pull. If that fails then I guess it'll be time to upgrade it to either a H80 or ghetto mount a H100 in there (case is pretty old and only has 1 120mm fan mount)

Eh, it probably wouldn't make that much of a difference if you could read the text on the IHS clearly, but you never know; I overclock, so every degree matters for me. I wouldn't remove it until you get the new paste.

And maybe push/pull for the future, but if remounting the cooler doesn't bring normal temps, it's most likely dead. Try plugging the pump into a different fan header.

And for rads, yup, you want fans with high static pressure.

I tried the chassis fan header, the full speed header and the cpu header, all of them at 100% speed and they all ran at 4470RPM too.

Damn, well if reseating doesn't help, I'd RMA it.

Can't RMA. Some moron threw away all packaging and the proof of purchase. Plus I'm not sure if they RMA in the UK.

It seems my prayers are half answered. My PSU died and I decided to get a new case too. The case comes with 3 fans so I'll try push pull considering I can find screws that won't go straight through the rad.

Make sure you get a decent psu - DO NOT SCRIMP here.

So the new thermal compound is giving me a 15 degree temp drop. Turns out the first thermal compound didn't spread at the top coz the top wasn't tightened enough. Only the bottom part of the cpu had paste on it. Now It's all good although idles are still at about 55 degrees.

Since my new case I'm getting comes with 3 fans, would push pull work better into the case or out? It has a front 120mm and side 140mm intake fan along with the rear 120mm one and a hell of a lot of meshed vents.

From my experience, there hasn't been much of a difference between intake/exhaust for the rad in CPU temps (little lower with intake), but you'll be pulling the hot air the rad is giving off when you have it as an exhaust, thus raising case temps.

Could be a weak pump. I have seen it happen before on low end closed loops.

I'll bear that in mind then. I'll need to find some screws lying about my house that are long enough to go through the fan but not through the fins. That'll be fun...

It's fine now that I've reseated it. Overclocked from 2.5ghz to 3.2ghz and ran Prime95 for 3 hours and it maxed out at 72 degrees. The idle temp is still worrying me though, 55 is a bit steep for idle, no?

My H60 with a single fan on my OCed i7-930 at load does not get as hot as yours at idle. Something physically wrong with the cpu-cooler mating or the cooler is defective - loss of coolant or pump not working properly.
