Thanks for the reply, Laptop Tech.

Yes, I discovered that the CPU is ‘throttled’ by my lpatop once it hits 70 degrees. I think this means I’m thankfully unlikely to have damaged the CPU by switching on without thermal grease.

Thanks for recommending X-23-7762. I’ll see if I can get hold of some. In the interim I’ve applied Nano Diamond.

For anyone interested, there’s another good guide on applying thermal
grease on the Arctic Silver website: http://www.arcticsilver.com/methods.html.

Ant,

there’s dried-out thermal grease on both the CPU and the new (second-hand) heatsink. Does thermal grease (or the lack of it) really affect CPU speed this much? Or should it not affect speed at all (i.e. should the CPU just overheat then stop)?

It’s possible that overheating affects the CPU speed. Probably the CPU slows down in order to prevent damage.
Usually I use this thermal grease: X-23-7762
Google this number and you’ll find it.

Hi,

Yesterday I replaced the floppy drive, speakers and volume controls and cooling fan and CPU heatsink (without applying new thermal grease) in my Toshiba S1800-314. Today, my laptop is running at about half the speed of normal.

Just looking again, there’s dried-out thermal grease on both the CPU and the new (second-hand) heatsink. Does thermal grease (or the lack of it) really affect CPU speed this much? Or should it not affect speed at all (i.e. should the CPU just overheat then stop)?

Software-wise, there’s nothing slowing the laptop down: swap file is fine, no suspicious processes, etc.

What are the best recommended greases or types of grease laptop CPU’s?

Thanks!

I have the same laptop, Acer 5100. I was thinking about doing the same but thought if I am going to go through the trouble to taking my laptop apart, I might as well replace the CPU. Do you know which CPUs are ok to use.

I was thinking AMD TURION MOBILE 64X2 2GHZ – HP PART# TMDTL60HAX5DM as I can get it cheap.

Any help much appreciated.

Thanks

Mike

Never mind, I broke the screw heads off… though I still need to buy the thermal grease, because I wanted check if it needs to be changed at first. Thanks for the tutorial anyway

I wanted to apply a new thermal grease on the laptop processor, because it was overheating, but the third and fourth screw on the processor have stripped heads and their screwed in really tight. I have no idea how to unscrew them. I tried putting a rubber band between the screwdriver and the screw head.. that didn’t help. Right now I can’t afford buying a drill or a screw extractor, so is there any other way to get the screws out? And if I somehow removed the screws, would I have to get new ones or I could use the computer without the two screws?

I did this and replaced my broken fan, and as a result my laptop is running much better. However while the temperature did go down (from 95+ °C, which was too hot to run the laptop), it only dropped to the high 60s °C. Is this normal? It still seems quite hot.

My laptop is a ~4 year old Fujitsu T4215.

Thanks, and Happy Holidays!
