I just attached a VGA HSF to my South Bridge with ASII thermal epoxy

Just one of the many mods that my computer will see. The process went quite well. I lapped the HSF with 600grit and shaved the mounting posts off. Place a thin layer of the Epoxy on the entire surface of the chip and carefully placed the Chip fan on it gentley pressed down with a twisting motion to get the excess out and ensure a flush mount. Then I placed a spare HSF on the top. And on top of that a can of spray paint for weight. And in 20-30 min removed and put back together. If anything it should cool the slightly warm chip. Any comments are welcome...

I hope your computer still works.

The excess that you were talking about has to go somewhere, hopefully not on any electrical contacts. ;)

well then lets see some pics:) . when you say you twisted it to get the excess did you just let it run on the board or what? Also what HS did you use?

By excess I mean I dabed it on there in a layer just slightly thinner than a credit card. the edges I thinned even more, like paper thin. The whole time I was trying to avoide any posibility of run off. as for pictures I do not have a ditigal camera. I think that one of my friends does. It will be a while till I get some pics of the finished product. The fan is a : (FAN-EC-VGA-B) (VGA COOLER BALL BEARING FAN W/HEATSINK) (PRICE $6.99) The AS thermal adhesive ran $15.99

I was lucky. I don't think that there was any excess. I was twisting it to get the air out and to get the heatsink flush with the chip. and fill in all the microscopic grooves. I wonder if i were to take it in to the local Inkleys photo shop, if they would take a few pictures of it and E-mail them to me, for a small fee.

heatsink on SB

I cut a square piece of blue anodized aluminum p2 heatsink (pins not fins) and lapped and mounted it on my SB. No problems yet. I think its mostly for looks than anything performance related.

Also, this is how I killed my AK31... by putting an old hsf on the NB that was too big. It contacted some of the nearby surface-mounted components and caused a short. No post, sinlge long beep. When I removed it, I knocked a resistor off the board. Doh!

Anyway, I added the heatsink piece to the SB of this new AK35GT-R, and settled for just adding some AS3 under the NB's hsf.

Do you think that I should place some ASII between the chip and HSF on the N.Bridge. Will it even make a difference. By the way i could not find AS3 anywhere if you have a LINK please share. I had to drive 1.5 hours round trip to Salt Lake City lastnight to get my ASII. I would have perferred AS3 but could not find it.

When I put a hsf on my A7V's northbridge, I had no place for the old greenie, so I popped it on the southbridge.

Doubt its doing much there, but its the thought that counts! Anyway, thats the best place to store that greenie...never know if I might need it, and atleast I know where it is...

TRUE! TRUE! It is the thought that counts, and for bragging rights LOL. I think that it is cosmetic more than anything. But it gave me something to do. AND OFFICIALLY VOIDED MY WARANTEE!!! I bet asus would love to see my try and RMA this board now!!!

I don't think it will hurt anything and all it can do is help. Obviously you won't notice a huge difference but something compund would certainly facilitate better heat transfer. You could also try artic alumina on the chipset if you think you will get it everywhere.

So you don't have to worry about getting artic alumina on pins and connectors. I am always woried about shorting something out. When I epoxied my south bridge, I had to position the HSF very carefully. Lots of things in the way. I used wood shims (ya know the mixing sticks) to keep a gap between the silver cap looking thing to the topright of the chip and between the AGP slot.

HERE is a good review of it. Yes it is non-conductive.

I had to remove the fan for it. For some reason it was affecting my computer in a manner that made it seam like the MOBO was fried. It worked fine for several days and then prevented the PSU from Functioning. Too strange for me. I would have added more pic's but my new digital camera's drivers were not fully functional with WIN XP PRO. So I had to remove it and uninstall it. I will try to get an XP compliant camera soon.
