I have a Dell D620 that is out of warranty. The fan spins up very fast sometimes and it has the nvidea chip set that has overheating issues. For the last few weeks the lcd screen has become pixelated and lines form all around it. The external monitor still works fine though. I though it was the screen but the Dell tech guy told me it was a common GPU\Motherboard issue. I took the keyboard off and saw the heat-pipe but didn't see any dust. If I buy a laptop cooler should this correct the problem or should I apply some Arctic silver 5 on a certain spot or use a speed fan program to increase the gpu fan speed or monitor temps? Anyone with a D620 have this issue? Replacing the motherboard is not an option unless I could find one for around or under $150 but I think they cost more than that.
 
a laptop cooler will probably help.. since its out of warranty might as well try putting as5 on the gpu heatsink..
 
I would also apply the new TIM and dust the hell out of the unit, I might also call dell back up since this is such a "common" problem and try and get them to fix it anyway....But it is dell...
 
Today when I ran the Windows 7 benchmark my cpu's core read 82C and my GPU read 80C using the Speedfan utility. However speed fan will not let me change the speed of my fans on the D620. Does anyone know of a program that will under Win 7 64bit?
 
Run awua mark or 3d mark 2005 that'd do it, or prime 95 for the CPU in good.

I am on a D630 for work and i've had it to bits before, pretty easy to rip apart and i know that when this starts to happen the best thing to do is get a coffee and sit with the laptop for a while take it apart and replace the heatsink compound (TIM) with something like AS5 (always my favourite but not others') and dust the hell out of it. You'll find it could operate A LOT cooler. I saw 20c difference on a precision M70 (without a laptop cooler).
 
so just pop the heat-sink off the cpu and gpu and put a pea size amount of arctic silver 5 on it?

Just be sure to clean off the old crap really good, of all the laptops I have replaced TIM on the OEM stuff is always caked on like a foot thick.
 
not to burst your bubble but you have a defective nvidia chipset in that machine. the Inquirer did a long series of articles about bad bumps and those fx chips :( you might be able to use that to get dell to help you fix it even out of warranty but i doubt it.

This.
Make sure you carefully twist the heatsink and lift off with ease. Remember to clean off the old crap properly, alcohol wipes are good for this, then dry and plop som AS5 on it.


Also want to add that we have several (10+) D620's at work all still working fine, not all of them must be defects.
 
There was a mix up with Dell and unfortinaly they can't replace it but the dell tech did tell me that buying a cooling pad and applying some better cooling paste would help alot. Can anyone recommend a good cooling pad for the price? There are soo many out there now.
