Replacing the TIM is worth a shot, I've got some Ceramique that's non-conductive.

some have used 12mm slim fans behind the cpu to keep it cool  ---  ( its only 12mm thick)

put it between the motherboard tray and the case cover at the cpu opening

I see your point in wondering if watercooling the vrm's would have any effect on cooling the socket temp, but I think it might make _some_ difference.

Looking at the thermal radar thingy (nice to look at, but that's about all it's use I can find... though the Sabertooth does not come with FanXpert in it's software bundle, it does work - i installed the version I got with AI Suite II from my M5A99X EVO)..... Anyway, where was I? wink.gif Looking at where according the software the sensors are, CPU and V-core 1 are close together, so close I think heat of one area surely influences the other.

Hence, I'd imagine keeping the V-cores cool(er) might shave off a few degrees from the socket temp.

If / when you remove the heatsink and replace the stock TIM, be sure to keep me posted on how easy it went and if you see any improvement...

For all I've tried, I can't seem to get my FX-4170 fully Prime stable (after 1,5 hours or so usually one or two cores throttle down). But the best stress test I've noticed in my case seems fully stable: Skyrim.

Ah well, I can live wth the way it is now biggrin.gif

Unfortunately that's not an option with my case.

Some good logic there. It's very probable that the socket temp sensor is seeing heat soaked from the VRMs that are 9c hotter, especially as the cores above are 9c cooler.

I'll be checking that TIM soon and will be sure to post the results.

Just updated to BIOS version 1101 on my R2.0. It deleted my OC profiles, and also tried running my 4 sticks of ram at 1T so I could not post until I removed 2 sticks and set it back to 2T.

I recently installed my Sabertooth and was excited to see the option of 1T/2T. I did not have that with my M4A785TD.

This got me thinking: does anyone know if AMD has thermal sensor bits in their chips yet?

I know Deneb chips didn't, and seeing the way core temps are now with bulldozer I still think that's not the case: it still looks like a guesstimate to me...
An idle temp lower than room temperature? Not to mention 0 or even sub-zero, at times?! (after just powering on cpu and mobo: 23 C, core temp: 0 C or lower...)

No, I don't trust core temps, unless under load, they might be close then...

But I do think I understand the assumption why the socket might heat up a bit more than the cores themselves, with proper cooling... (cpu -> cpu heatspreader -> good contact with a decent cooler = beter dissipation of heat from core to cooler)

Going from 1006 to 1101 I had to change my ram timings.
1101 likes them loose or it wont post.

But having them loose didnt make any chance to my benchmarks so iv got my doubts that they were even being set correctly by 1006.

Motherboard heat sink was easy to remove. Two screws on top, either end of the VRM heat sink, and two underneath the NB heatsink.





That stuff around the NB chip is like chewing gum! I've replaced that with some Ceramique and the pads on the VRMs with the stuff you get from EK with the GPU blocks.
