They also have the Noctua as well-

BTW, all the coolers mentioned so far are enormous. I hope you're getting a large case...

aevm, case size is not a problem. I got a Cosmos S case and am prepared to take off the side fan

Yes it's very good. The NH-U12P and the TRUE get a little better temps and noise levels in reviews, but nothing you'd notice in real life IMO.

This review shows the TRUE beating the CoolerMaster V8 on both temps and noise. For example TRUE gets 14.9 degrees difference between CPU and room, with 29.7 dBA, while the V8 gets 22.5 degrees difference using the same Nexus fan, with 29.8 dBA. That is, the TRUE keeps the CPU 8 degrees cooler.

This review shows the NH-U12P matching the TRUE in most benchmarks, and beating it in some.

Still, I don't think you need to worry. These 3 coolers are all exceptional performers. You'll be pleased with the V8, I'm sure.

I7's run hot, I've just installed mine and my TRUE ran fine at 4.0 but temps jumped to the 90s, which aparently is useable with these chips, but I just can't do it, I'm too used to Q6XXX temps(low 60's ect...)

I ran multiple passes in 3dmark and it was completely stable ran around 50 idle mid 70's running 3dmark but prime 95 would push it to well 95C.

I've got the bolt through kit on my TRUE so it's definitely seated properly, I think these things just run hot.

The V8 will probably do, but I wouldn't expect to run 4GHZ 24/7, but you should be able to benchmark with 4ghz and run it at 3.6-3.8 24/7 easily.

Agreed. In real life the HDD is often a bottleneck and you'd end up with a stock CPU and an overclocked CPU finishing the same job in the same time. I see that with my Q6600 when compressing DVDs for example - it's not reaching 100% usage. I'm not even overclocking the poor thing any more

The one I've seen used in reviews most often is Scythe S-Flex SFF21F:

Why do you hate it? I installed it, but have not overclocked with it yet.

Prolimatech Megahalems should to be one of the best in the market right now.

You can get it on ebay if it is sold out on the online stores.

Ok to everyone wondering about this 4.0ghz overclock .... it can be done in the standard heat sink fan from Intel .... as my i7 920 is at 4.2ghz standard heat sink fan ... but i also have 400 mm fan blowing directly on it .... And my mobo out of its case ...I am also wondering what the best one out there is that's not really expensive ... Everything i see is around 50 bucks and doesn't look much different the standard one...

Finding 1366 heatsinks is not a problem. They have been available since October of last year. One of the best ways to find reviews and articles about them is to use the embedded search feature at frostytech.com. Here is a link to the search results:

I have 2 of my I7 920 (D stepping) running at 4.0G with the TRUE heatsink on them. The max temps I see are 71C under small fft's in prime 95. These systems are rock stable and have been running running Seti 24/7 for the last 2 weeks with no issues so I know it can be done.

my v8 goes to 4ghz but the temps are at ~80c i blame my crappy ambient temps. should get a better case.
