Overclocking the Core i7 920

[PH3N0M]

Hey, that's nice! Cheap, too! What do you think about this for an aftermarket gpu fan? It's the ARCTIC COOLING ACCEL X8800 Fluid Dynamic VGA Cooler and retail on Newegg is $43. Reviews have posted temperature decreases by as much as 20c...!

If you were going with a water cooling loop, you could just add GPU blocks. Would end up being a lot better since it would be interfacing with your current setup.

Wouldn't that mean I'd need a larger reservoir and/or radiator?

Possibly, I really don't know a whole lot about WC in depth, that's aspire's forte. If you would look through his guide, you should get a better idea.

Hmmm, so many choices. :? I really don't know where to begin. I'd really like to go with liquid cooling but I worry about leakage and something shorting out. I guess I could always superglue the tubing to the blocks and reinforce it with a clamp, right? I know there's non-conductive liquid I could use but I've read where others have used anti-freeze and achieved even lower temps. I dunno though, it's a lot to think about because I want to go the right direction. At this point in time, I'm not sure I need liquid cooling because of the fact that I only play a few online games and don't really do anything intensive which generates a lot of heat.

I really wouldn't trust those temps. For one 80c is really high. The temps were really weird too...really inconsistent. Plus add in the fact that sometimes 1 core would be like 30c lower. Anyone else notice that? Unless i'm missing something I would say faulty temp sensors.

BTW you need to test all cores (with hyperthreading) at 100% load and see what your temps get up to...

he's only at 50% load, so some cores are stressed and the others are lightly stressed...but those temps will be higher if load is at 100%

I ask because I increased my BClk, whatever that is, from 133 to 177.

I just realised...177x20= 3540Mhz. So he must still have turbo mode on, which also accounts for the differing temps, and why it has done this well on a stock cooler. So, Ph3nom, your overclock is actually only 3.54Ghz, with turbo mode on - so the peak might be at 3.8Ghz.

Most people turn off turbo mode to make it a stable overclock, i had assumed you had done the same.
