post #11 of 17
Sunbeamtech core-contact 120? It snaps right onto an AMD socket..I have my old 92mm version zip-tied on top of a 2500K atm..working nicely biggrin.gif

BTW, couldn't you mod the 212 to fit the 940 socket like they've been doing for G34 sockets? Should be simple enough to adapt it.

Oh, thank you, thank you! Now that I look at it, seems straightforward. I cut up and drilled a couple L brackets I had lying around and they worked fine. Now I just hope I can cancel the replacement order--it hasn't shipped yet, so hopefully can, and it means I'll cancel the RMA, so they should want to cooperate.

I didn't take a pic of the brackets yet, but I did of the delidded opteron:



Delidding wasn't too hard once I got the hang of it. Just went around the edges again and again with the razer blade and a little extra work on the corners. I left only a little of the blade sticking out so there wasn't much danger of it going in too far.

I had no idea the IHS was so hefty. Are they all like that? I thought it was just a thin cover kind of thing, but it's not--it's a solid block of metal, probably 1-2 mm thick.

I have to say the hyper 212 plus's I got... are they all like this? There are very noticable gaps around the heat pipes in the surface. So, I delidded one opteron, heatsink direct on die, and left the other alone. The delidded one is running hotter--maybe 8 C or so. I think it's because the heatsink surface. I wonder if I lapped the heatsink surface if it would fix it. Though I'm not sure lapping will fix gaps. Anyway, I'll probably put the IHS back on. Then it will be interesting to see if new TIM will make temps better on that one. I'm using MX-4 thermal compound.

Yep, the gaps in the 212+ are normal. That's the difference between the 212+ and the Evo, the latter has a solid block around the heatpieps - I think its like a 5c difference in temps, maybe more maybe less.
But your temp difference with the IHS and without is probably down to the smaller transfer surface and the gaps between the heatpipes - I'm assuming you filled them with TIM first?

Yes, I used the credit card thing to try to scrape around TIM all over the heatsink surface first (tinting the surface is what I've seen it called). This was just a practice thing, so I'm not too concerned about the final performance results, though under load temps are getting over 60 which is higher than I would like.

It made about 2C difference in my temperatures when I lapped the 212 Plus. It was already doing fine, I was just curious if it would help.

I thought I'd post a follow up. I put the IHS back on the delidded one. It's still higher temps than the other CPU, but I didn't check before hand, so... they might have been that way before. I think it did lower the temp a little from without the IHS, maybe a few degrees. It's not a good test of IHS vs. not IHS because the surface of the heatsink has such gaps. And I had to mickey mouse mounting them.

Oh well. Overall, it wasn't that crazy once I figured out how to do it. The heatsinks do get really hot, though (probably need better case air flow). Unlike my sig rig which is water cooled and I'm wondering if it's doing anything because the air, water, etc., all stays cool even when the CPU is running 60 C all day.
