T43P Way Way Too Hot, Help!

[dyoes]

My temps just keep rises when playing a game, I exited the game when it got to 75c and im sure would just keep rising.

Started this T41 to T43P upgrade and bought a T41P long fan but when I recieved it the GPU heatsink part wasnt as big as the T43P long HS fan GPU and the temps were bad so I bought a T43P HS fan, seems it has to be to the thermal compound. I heard Artic Silver 5 was really good so I used that.

My questions what temps do your T43P run at, what thermal compound do you use, and any special mods to make this run cooler?

Im not interested in other T4X temps, I know they run great my T41 ATI 7500 ran at 38-42c and in the 50s at full load playing games.

Thanks

The T41 long fan has a plastic sheet that covers the pad that contacts the GPU. That sheet needs to be removed. If you have M10 graphics processor, you need a special fan without a plastic sheet . For everything except M10, be sure to remove the plastic sheet.

I think you confused some things,

The T41 long fan doesnt have that pink plastic bit Its the T43 long fan that does, and you confused the M10 and M24 I think.

I have bought and tried the T41 long fan and if you remove the black rubber thing for the gpu it wont touch, however you can remove the pink sheet from the T43 long fan but theres a very very fine layer of black stuff. Wonder if I should remove it all and put down some actice silver 5 for the GPU....?

I don't mean the black stuff. I'm talking about a thin plastic sheet that protects the black stuff for shipping. Look at page 105 of the service manual.

My IBM T43p is currently running at 90 degrees Celsius (Roughly 200 degrees Fahrenheit). Of course I also am using 100% of my CPU doing video encoding.

Obvious to check but make sure the fan isn't blocked with dust.

Yes some of the various long fans have plastic pads between the underside of the fan and top surface of the GPU, and yes they aren't great at transitting heat to the heatsink.

If you want to improve the cooling, remove the pad and measure the gap that will be left, and to buy some copper (not brass) sheet off eBay of the same thickness to fill it. A Dremel cutter will easily cut it to size.

Don't use Arctic Silver (or any other heatsink compound) to fill the gap, since heatsink compound is there to fill the tiny imperfections between mating metal surfaces and should be very thinly spread on both sides of the copper sheet.

If your CPU is running at permanent 100% then it will become very warm regardless of what you do. You can improve the cooling by removing all existing heatsink compound from the CPU and Fan heatsink using alcohol based cleaner and again applying a very thin layer of AS5. Don't use a thick layer as it will make things worse!
