Gotcha - but it might be good then to specify what the ambient was during the testing. Otherwise excellent review. Very interesting to see just how crappy the stock Intel HSF really is compared to even the low-end aftermarket coolers.
According to the results of occ the findings here are identical. However @ occ they compared not only idle and load, but over clocked performance as well. I think it is relevant considering the potential shown in the 1st generation 1366 batch for mischief and most people buying a 920 tout of their stamina and head room.
Idle temps of 20 degrees on the stock cooler... with a 3.6 overclock and 1.3v??? Come on!!.. Where were you based, a walk in freezer? I can't get lower than 40 degrees on the stock cooler with a 920, and it's not overclocked.

[Off] Damn idiots not reading the article... The temp display is in DELTA T, as in DIFFERENCE between the CPU temperature and the AMBIENT temperature. If it's 20deg C in the room, then the CPU temp will be 61deg (for eg).

Great article! So DHT coolers win the day on the "Value" category ;) Very cheap to produce, and they don't have to be extremely careful with the base, as long as the heatpipes make proper contact with the IHS.
I`m pretty happy with my Sunbeam Core Contact Freezer. Even works as a passive cooler for my E2140, with 3 80mm case fans, all set to minimum on my Zalman ZM-MFC1 Plus fan controller. 8deg C plus on passive.
Looks like I will be picking up one of those Akasa Nero coolers for my i7 920 soon.
Thanks for the article Bit - this is exactly the thing I was after. The TRUE looks great as ever but at over twice the price for a relatively small themal performance increase is getting on to be a joke.

And you verified these sizes as correct? People do make mistakes you know.
And by simply quoting the sizes on the box, you're assuming that all manufactures are measuring the same way. Is it the total height of the HSF or the height above the MB?
I still say a table would have been nice, but then maybe that's going to appear when the article is copy and pasted into the next CPC issue?

Why not just post the absolute temps recorded, and just have a footnote on the graph stating the room's ambient temperature. Even after reading the article (albeit rather hurriedly) it misled me, and judging by the posts above, a couple of other people as well.
It would be no more messy... it would just just be a different set of figures.. but a set of figures more in line to what RealTemp would report to you in real life if you were to buy one of these coolers.
The TRUE would just be 34 to 66C instead for example.
Incidentally, you really ran that chip for 30 mins at 98C with the stock cooler?

I imagine its because the ambient temperature isn't constant for all the tests, ie for one test it might be 21C, another its 25C. And so to add that data into the graphs involves either adding the ambient and actual cpu temps for each test (idle and load), or making a 3D graph, which isn't the clearest of things on a 2D display :(
actually, this has given me an interesting thought - how much would the ambient temperature affect the deltas? are you going to see a bigger difference in a 30C+ room, or in a room at 20C etc?
We've been informed by Cooler Master that our review sample of the V8 was an early release sample. All the versions of the cooler now on sale ship WITH an LGA 1366 bracket. As such we've editted the review of the V8 in the super test, and amended it's score appropriatley.
I can understand why we have air-cooled reviews separate from water-cooled - $. However, air-cooled users need to be aware that there's an interesting "inexpensive" CPU cooler out there that's WATER cooled - the CoolIt Domino. For the price I have to wonder why not go that route? One huge advantage I see is that air is routed OUT of the case by the cooler. That leaves the case temp affected by one less 130W heat source. There are reviews galore out there on this unit.
nice article.... funny thing I've used Zalman coolers on some hd 5850's ..took shroud off because it looks better without it.. now you tell me it cools better...cool

i have an ASUS Silent Knight II for my Core2Quad. I am wondering if i can use it for my new Corei7 950.
maybe buy mounting brackets from somewhere?
