Thermal Past Upgrade...Worth it?

Changing the paste does not void the warranty, as long as you don't screw up the mobo. I'm not sure where the shim would fall under that, though.

 

Couldn't you just remove it before you send it in for warranty? I'm planning on getting an i7 and obviously theres going to be way more heat.

 

hey guys do you think this sand paper will do the job?

Btw for those who are getting crappy temperatures by replacing the paste, it's probably because you aren't applying it on the whole copper part of the heatsink. I changed the paste today and got really high max temps then added more paste and spread it around then the temps went down from the stock paste. Anyways does it matter which shim to get from those ebay dealers? One is 5 bux and one is 2.50.

 

I just bought a copper sample pack from Amazon and cut my own. It's a soft metal so it's not much a hassle.

 

yeah just go to the hardware store or something.

What did you use to cut it though, Forge? no pun intended. wire cutters really tend to suck like worse than pliers, but copper is really soft so i dunno.

metal shears however will cut through stuff like you've never imagined. a good pair will make a clean cut in some like 16 gauge galvanized steel plates.
yknow just in case anyone needed to know that...

 

I used to have a pair of metal shears, but those somehow disappeared.

I found out that kitchen scissors can cut through the thinner sheets just fine.

 

seriously? mine disappeared too! what the heck...

edit: sorry, useless post, carry on.

Anyway, the mod seems to be working quite nicely. CPU is sticking around the high forties and low fifties, for the most part, and GPU is mid forties.

 

I have the pictures that were on page 12!!!
I downloaded them a long time ago(before I got my GX640), so I could upgrade with the pics offline.

Here they are in the order I found them on page 12:

Thanks so much bro

I'm looking for this laptop, lets hope I can find it

 

Hi guys,

I also did the copper plate mod for my ATI HD5870 since my idle temps with AS5 were around 85°C (only one half of the die had contact to the heatsink).
I used a 0,6mm thick copper plate I found in my workshop and cut it to 2x2cm (~0.8x0.8"). Then I bought P600 and P1000 sandpaper and polished the plate for some minutes. Finally I used AS5 on both sides and put it all together as it is described in this thread.

Seems to work great! The idle temp is now at 53-54°C but as far as I know the thermal paste needs some time to take full effect.
After 5 minutes of Furmark benchmark (1280x1024 (FS) - MSAA: 0X) I only reached 85°C.

So thanks for you good ideas! I can only recommend it!

 

What thermal pads did u use, and what thickness are those thermal pads?

hi all,

i have buyed some copper shims. ill get it in 2 weeks in my mail diliverd. does it better tranfer the heat than mx 4 thermal compound alone ? i have searched some forums and they told just need to but some copper shims 2 x 2 cm and depht of 0,6 mm and rub it up with p1000 sandpaper. place it between the gpu and the heatpipe cooling with some thermal compound. can someone says iff this is the good way.

thanks,
robert
