Heatsink for E8400

Custom / Ep45-ud3p

Specs: Microsoft Windows Vista x64 Home Premium, 3 GHz / 8189 MB
I'm looking for a heatsink that will let me safely overclock my e8400 to 3.6GHz or so. I've read a lot of reviews that say this speed is even possible on the stock heatsink, but even at idle my core temps are close to 60C with the stock heatsink.

The popular choice seems to be the Arctic Cooling Freezer 7 Pro 92mm Fan. It is cheap and apparently works quite well.

Looking around, it seems that the following also get good reviews and are about the same price:

-XIGMATEK HDT-S1283 120mm Rifle CPU Cooler
-MASSCOOL 8WA741 92mm Ball CPU Cooler
-Rosewill RCX-Z775-EX 92mm 2 Ball CPU Cooler

Does anyone know if any of these will have trouble fitting on my ga-ep45-ud3p board?
Any other comments on the above list?

I'll probably go with the freezer 7 pro, unless there is a compelling reason to select one of the other 3.

PS: Height shouldn't be an issue as I have 15+ CM from the motherboard to my case side.

60C at idle indicates one of two things...the heatsink wasn't properly installed or the temps aren't being accurately reported. Apparently the E8400 is known to have issues with temp reporting:

Try updating your BIOS. The latest version states "Support ITE8718 KX"...that relates to H/W monitoring so it *may* correct temp readings.

The heatsink probably isn't on right. The little plastic pegs that are used with the stock heatsink broke, so I have it held on with bolts right now. This is good enough for the time being, since I will be upgrading to one of the above heatsinks soon...

If you can't get your current HSF to work properly, OK, but you don't "need" an aftermarket HSF to be able to overclock. Also, make sure to use the proper amount of thermal compound. A tiny dab is all it takes.

If it was my system, the 1st thing I'd do is update the BIOS. Then I'd remove the HSF, clean it, come up with a decent way to secure it to the board, apply a dab of paste, reinstall it, then begin overclocking.

As jam mentioned, the E8400 is known to have issues with temp reporting. I would also try a program like Real Temp to see what temps it gives for the cores. I get ridiculously incorrect temps for my E8400-but not for the cores, which seem to be accurately reported by Real Temp. Also check the PWM temp-that should be closer to the actual processor temperature.
