E6400/P5N32-SLI SE Deluxe/Thermaltake HR-01-775

[TedKord]

According to Core Temp, my E6400 ran idle at about 54C with the stock intel sink/fan.
I was able to OC to 1300 FSB and 850 memory with stability. I was happy with this speed, as it was essentially E6700 speed. I was only worried about the heat.

So I purchased and installed the TT HR-01-775, using AS5 as the thermal interface.
(Cleaned the processor of thermal paste thoroughly with 91% IPA). Now it runs idle at about 52C, and I can't OC past ~1220 FSB. Frustrating!

Guess I'll have to try active cooling on the heatsink - time for a new 120mm fan, and to pull out that duct. If that doesn't work, I'll try resinstalling the stock HS with AS5, see where that gets me.

Any other ideas? Thanks.

That is not an OCers board. You're lucky to even get 1250FSB.

yeah it maxed out at 320fsb quad pumped = 1280fsb max...

i doubt even the C55 nforce 590 will 400fsb ...

I know, that's why I was happy with the 1300FSB. But I can't figure why I can't get it anymore with just a heatsink change, especially one which did lower core temperatures, albiet a tiny amount.

One theory I came on last night is that the duct is preventing airflow over the north and south bridge heatsinks, and they're getting hot. If that's the case, going to active cooling on the processor heatsink should cure that problem.
