My AS5 pumped around Heat pipe/Heat skink mod on 7800GTX.

Hi people, just put my 7800GTX in my lappy (should have got this card in the first place when i ordered but oh well) anyway i decided to inject Arctic Silver 5 in around the heat pipe. Aswell as applying it normally (not injecting) to the ram and GPU just like the directions on AS5 website. I figure more contact the copper heat pipe has with the heat sink the better. Anyway was running at about 45 degrees idle now Vs 49 without the AS5 pumped all around the GPU heat pipe. (Picture is attached)

And I also read someone here mentioned to use the keyboards back as a heat sink to which I did...I peeled of the plastic just above the GPU head sink and put a big lump of AS5 there too.Now the keybaord is also a heat sink. (crazy I know but it seems to have helped,besides you dont see this anyway)



Now Im just O'Cing my GPU to the max I can without artifacts etc. So far my results are as follows (Im still using Dell drivers)


3D05 Driver ClockSpeed Max Temp Artifacts
----------------------------------------------
6575 78.51 StockCLK Max Temp 69c -
7367 78.51 450/1250 Max Temp 75c Artifacts? N
7492 78.51 455/1300 Max Temp 77c Artifacts? N
7528 78.51 460/1300 Max Temp 75c Artifacts? N
7649 78.51 475/1300 Max Temp 77c Artifacts? N

Btw im only testing for Artifacts for 20 mins in ATItoll beta 9, becasue I dont have all day.Later I will settle for a clock speed thats good for 20mins and then let it run all night to check if it has errors.

Hmm, I wouldn't think that would help too much, but good luck with it. Seems to me the fans/fins of the normal heatsink actually transfer the heat to the enviornment. The keyboard would just get hot and not really radiate all that much heat away from the GPU.

Your temps are better than mine, but mine has always run hot--OC's fairly well though.

Wow, how many bottles of AS5 do you have, geez...

No tubes of AS5 left now..well call me crazy if my temps for me have dropped by 3-4 degrees,then I think thats speaks for itself no?

Has anyone else tried this ? My GPU in i9Fangui is 44 degrees now. I remember my 6800 ultra was idle at 54.Big diff the 7800GTX is a cooler unit.

Well the temperature drop could be due to a number of other things: lower ambient temperature or maybe when you opened up the laptop and cleaned out the fans.

Maybe the environment is colder.

Anyways, 3 or 4 degree change is not breath taking, too many factors to be taken into account.

In addition, the extra 3 or 4 degree might have been transferred to under the keyboard, and etc, where minimal temperature were initially intended; therefore, you lower the gpu by about 3 or 4 degrees, but increased the chance of other things breaking.

Your only suppost to apply a very thin layer. More does not equal better with AS5 and you shouldn't of put it on that memory ither because AS5 is slightly capacitive and can cause problems if it gets in contact with anything. You should try following the directions on Arctic Silvers website. All you did was waste a ton of AS5 for nothing. All you needed it on was the GPU core itself. Not the entire heatpipe lol.

I had to take down a couple of computers this week where the previous users had TRIED to apply AS5 and used WAY too much and it was such a total mess. I wanted to just slap them.

Becare AS5 is conductive so make sure none gets on the Motherboard. Not a bad idea, but a bit messy IMO.

No no the GPU I have applied the AS5 exactly like the instructions on the website. Just a little bit in the middle. and cleaned it with there cleaners both steps 1 & 2. Yeah it must be the room temp and the that dust in the fans.Thats it. Well disprove this all you like.The fans were clean and the 7800 new..and I tested before and after and the temp did drop by 4 degrees.

Yeah its a little messy looking, according to the website AS5 is not very conductive,dont see how though it contacts silver.

I don't think AS is conductive..........

AS5 takes several days to set up and temps are usually higher when first applied so your drop in temps could be any random number of things that have nothing to do with the AS5 you applied all over the heatpipe.

Yea its slightly capacitive but suppost to be non conductive.

I don't think it help much, I have the same Temperature drop by just applying AS5 the normal way. I have a 6800 ultra and everyone knows that the 7800 gtx is cooler than the ultra. So like the other guys says your just wasting AS5. Just apply AS5 correctly can drop GPU temperature greatly. Cpu idle 28-32c, w/AS5 Cpu idle 25c, Gpu idle 49-52c, w/AS5 Gpu idle 44c-45c Load for playing CS:source for several hours was at 70c, O/C 500/1200. So there is really no need to waste all that AS5. Not to mention could cause problems then its suppose....
