I recently did a small mod on my mb. I removed the north and southbridge heatsinks and removed the old dried up thermal crud that they use. I can't see how that old stuff was even doing any good. I reapplied OCZ Freeze Thermal Compound in its place. I also applied micro heatsinks all throughout the mb using Arctic Thermal adhesive.

O I like that, can you post a link to the sets you used to do this please.

2x 5870 HD @ 1015/1300 Asus reference
Dual OS win 7 x64 ultimate & win 7 x32 Ultimate (bench os)

Here is the place I got the micro heatsinks. However I removed the thermal tape and used thermal adhesive.

Here are some temperature results after doing some work on the mb. I am very satisfied with the results for air cooling. These temps are with stock settings on cpu and 100% load on cpu.




These are my idle temps.

so are all 4 cores working 100% and for how long ?

can you run it with the Everest stability test and time it for say 6 min and see how she does? Post a SS of the test at 6 min with listed temps would be great.

I am a fan of cheap but effective cooling mods and I like what you have done. Great work.

I would love to mod my SB and NB on my motherboard, So will be getting with ya on whats best to get price/performance wise.

Look at the top pic its on there. I have run it before for 8 hours and the numbers are just about the same. I am still using the stock nb and sb. I just replaced the thermal crud they used and added a bunch of micro heatsinks to mb. I would eventually like to replace the mosfet, nb, sb heatsinks, however I cannot find any information for what is compatible with a 780a chipset. I think I could use the ones for a 780i, but I want to get it figured out before buying them, so I don't get the wrong ones.

Well I am going to do additional work to my mb later today. I have purchased 2 aftermarket heatsinks for the NB,SB and individual copper heatsinks for the Mosfets. I have already lapped both heatsinks.


Here is the mb with all the new heatsinks added.

Hi Ed..

I think if I were you I'd have used those HSF's the other way around the SB generates a lot less heat than the NB does, the larger surface area of the Heatsick your currently using for the SB would be more beneficial on the NB.... it would also maybe be easier to access the CLR CMOS jumper with the smaller of the 2 heatsinks on the SB...

But I really like the new Heatsinks, and your temps are really superb, around the same area as I get with water, what's your CPU speed for those temps... the 39C Load temp I mean....

Kaz,

Unfortunately I could not reverse the 2. The one on the sb has to be there because it is offset to allow my video cards to be in place for sli. Otherwise the one on the sb would be in the way to put a video card in, at least for the big GTX 295's. The temps I had were at stock settings. I am sure they will be slightly higher with some oc. But would be good with just using air cooling.

Here is a sb cooler, you can see it is offset.

of the smaller heatsinks I have several left over after I did the modification to my ECS board and I am going to place them on my Asus

Well, I really am impressed with what you did. Thats amazing, and well done. I recently decided about doing it, and a concern was to use the thermal "tape" or not, I agree about replacing it with proper thermal adhesive. Also you provided the link to the hs's thanks! Anything that you did that you rather you had done differently? Any tips would be helpful!

Thanks.

For now I am satisfied with what the heatsinks are doing. They are doing alot better job then the stock heatsinks and heatpipes. They only feel warm to the touch now instead of hot. I may go with a different NB heatsink that is similar to the one on the SB. Just so it has more exposure to the air flow in the case, instead of having a small fan mounted to it. Other then that I am totally satisfied in the results so far.

I have to ask - what's the secret to the lower MCP temps on the stock board? I just took off the pipes this weekend and AS5'd them. I went from about 70C stock to 63C, and I'm hoping with cure time it'll drop lower. Granted, my case is garbage, and I'm running it with the side cover open and a spot cooler on the MCP, but I won't even think about P95'ing the system until I can bring it down some. I expect to get my HAF 932 and chipset coolers within the next 2 months, and that should make things a bit better, but until then, I'd like to avoid frying something...

thats one of many ways mate. thats my nf980 g65 from MSI in my other tower. the fans you can see are aftermarket grapchics card coolers for the old nvidia 6000 series cards. i put some AS'5 and then glued them down directly to the chip wafer with heat transfer epoxy. my mcp temp at a high overclock is now only 35 celcius

What are you going to do when the fans die?

way to rain on his parade, man. lol .. i kid i kid

......

but ya thats not gonna be so cool when the fans decide to give up....... see what i did there?

I just called it like I saw it. A lot people have great ideas, but don't think things through long term. He may have gotten lucky and placed just enough epoxy to hold it down and it will come off with just a gentle twist, but you never know.

When I do things with the epoxy/TIM combo, I use a toothpick to apply the epoxy and I only apply it to the corners.....just enough to hold....not enough to permanently bond the parts together, and I can usually just twist the part off if need be.
