About LinkBacksJust received my TRUE - I'm at work but have opened it, checked it, and found that placing the base of it on the desk, I can rock it slightly from side to side!
I've not got anything to compare it with, but isn't it supposed to be pretty much flat?

It's not that uncommon, but it shouldn't be excessive, usually if you use a good thermal paste there is no problem.
If you're worried you could lap the base to flatten it (this involves sanding the base down), some lap both the hsf and the cpu to decrease heat (a video of how CPU/HSF Lapping Guide by DrMrLordX -- Revver Online Video Sharing Network) , be aware this will void your hsf/cpu warrenty.
I think it's a bit of a joke that they make this incredible (not to mention incredibly expensive) heatsink, and mess up on something as trivial as giving you a flat surface for the thermal contact.
I think they were intended to be convex to match the heatsink of the CPU.

i'm currently lapping mine as it's that uneven only a small portion of it actually makes good contact with the cpu
that's their bs excuse though, they are not even as they solder the pipes to the base after they have finished the base and the soldering then warps the base, pee poor manufacturing and complete lack of care regarding quality control tbhOriginally Posted by EzyRyder
Well I hope that is the case. I've not got the resources (not to mention the time) to start lapping things. Although I don't see any mention of this convex base in their FAQ...
I'm worried now, mine should have arrived in the post this morning. I don't much want to go to the hassle of lapping it before I use it.

That is why i stayed away from the Thermalright. Most people i know that have used them had to lap it for better contact.
Well mine seems to be working fine, I'm running between 5-10C cooler than I was with my AC7 Pro.

Well I'll give mine a go tonight, I've got some Arctic Silver 3 left over from a few years ago. I'll apply it more liberally to the edges to make up for the less contact there. If it's not great then I guess I'll have to resort to lapping it.
finished lapping mine yesterday, here's the various stages
clearly shows that only the centre bit was making contact
still not completely flat edge to edge but flat enough to cover the cpu completely, that's after 1200grit but it's a bit smoother than that now as did a bit with 1500grit after
before and after shots
what is your before and after temps? majority of people that do lap it don't exactly reduce the temps that much despite the surface not being flat.
Recently upgraded my system to a quad core (X3210) and am using an Ultra 120 Extreme to keep it cool... However core 0 and core 1 are consistently 4-5 degrees hotter than cores 2 and 3 at idle... Is it worth lapping the base of the ultra 120 to see if it helps?
that's a common thing with quad cores, and it's always core 0 and core 1 that are 5'C hotter..
my core 0 and core 1 are still hotter than 2 and 3 even though i'm running 2 and 3 at 100% and the other 2 at idle.. it makes no sense, but it's a common thing..
lapping may help though yeah.

Thanks - it's my first quad core and I really wasn't sure if it was normal (I only put the system together on Thursday). Temps are a bit warm (39-44 idle, 59-65 sustained load according to coretemp - at 3.2GHz / 1.26v) so I may lap the base at some point anyway but if it's normal I won't bother just yet - I was worried that bad contact was causing the ~5c difference.

yeah, i get 39 - 44 at idle also.. with a Q6600 at 3GHz
if i take the FSB to 334 it won't boot but at 333 it will :S
quite strange.
40'C isn't really that hot though.. 4 cores, only 5'C each really above room temperature.
i only built my machine at xmas.. and it was my first ever build, was with a 1.9GHz P4 with 256MB of RAM before this, the difference is sooooo incredible! on xmas day i don't think i move a muscle, apart from my arm.. hehe
i'm guessing by the code of your Quad core that it's a Xeon, yeah?
are those things any different to the Core 2 Quads?
