Chastity's Repaste Experience

As DCX mentions there will be a difference between the temps and I saw 9oC difference with AS5 even though I repasted correctly its just the way it is but with ICD I only see 2oC difference max so I got away with a jolly good repaste.

How did you apply the paste did you use the pea method? Did you warm up the ICD before applying it? 20oC is too much go back and try again and make sure you reseat the heatsink correctly and apply the screws corner to corner 1-2-3-4, clean off all old residue with alcoholic swabs.



3mm pea method.

Jep, jep and double jep. Remove all the paste and used the pea method. Warmed the paste but it did not seem to be any softer. Used water at about 50c ...waited 5 min then added......let it stay for was it now 3 or 5 min and then but the heatsink on.

Ou well better luck next time

Let it stay? What do you mean by this?

As soon as you apply the compound to the GPU you must reseat the heatsink 'immediately' as ICD will set within seconds once it makes contact with the cold surface.

That could be your problem you might have a hardened blob that has not reached the outside of the chip. Once applied ICD turns into a putty type substance very quickly.

Sry wrong way lol after i added the heatsink waited for 3 or 5 min.

Only way to find out is to whip it off and have a look at the application and repaste again. Things dont always go to plan the first time round.

It is not critical to warm the paste for application. I just did a CPU paste, and never even warmed the tube. It's also so super conductive of heat that once you place it on the CPU, it transfers its warmth to it. I watched it cool right up during application.

The warming is to just make it easier to squeeze out and hopefully shape into a ball.

Yes its much better to apply when warm. First notebook i repasted with IC7 i did not heat the paste and man was it hard to get it out of the syringe.


Was reading the alienware posts and found this M17x R2 full internal cooling mod - huge improvement!!!

How healthy is it to add paste to the vram ? I know Dallers said not to but just asking as they seems to have done it with alienware. With IC7 there should be no problem of shorting something out. Also the heatsink will cover the GPU better? With my first JH repaste i replaced my pads with 1mm 5W/mk before but it seems to force the heatsink up abit leaving me to belive that its not pressing on the GPU as it should.

i think someone on this forum used 0,5mm thermal pads or am i mistaken?
A nother thing that one of my lecturers said was why not use 0.5mm copper spacers on the vram like the GPU has on it.

Myself and Tijo posted about using 0.5mm pads and yes it does help the heatsink to sit better (more flush) over the GPU because mine was raised up.

People have used Thermal compound and copper shims on the VRAM but do so at your own risk I wont recommend either because Thermal pads are much more reliable when covering several sections evenly, you may see better results by using the alternate methods but I would only do them if you are confident you know what you are doing.

Hey so i repasted my GPU about a year ago using IC Diamond. At first, the temps were held steady at like 60 and it was phenomenal. Now, however, the temps can get back up to 100 during 100% load and the GPU and CPU fans are pretty much always revving. Could this be just due to dust buildup in the heatsinks? Or do i have to repaste my card :P
