Toshiba C660 IGp chip get really hot.

[Bisketti]

Hi I am working on a Toshiba C660 and the IGP chip gets really hot, the fan is running constantly. I have measured the temp at 67c dos anybody know if this is normal also I cannot find any short circuit caps around it but there are 2 caps on the igp itself reading short. I suspect the Chip may be faulty, what do you guys think ?.
The set is running normal just very hot.

Replace thermal compound

I have tried that also placing copper shim aswell I think maybe the IGP chip itself is faulty.

Does it work fine? Let it be.

I like your sentiment.

Pretty sure if there were shorted caps it would not function at all.

Honestly, some IGPs do run that hot. Maybe a dodgy thermal sensor? I guess the only way to be sure is if someone else with a C660 with that motherboard chimed in.

try to clear cmos by removing battery... helped me few times...

I have already Updated the bios and the ec using external programmer, but maybe its normal just seems strange it would be that hot with the fan running constantly. Whats the best util for monitoring temp of Gpu? would speedfan do it ?.

Hm, how hot is the air that is coming out of the fan/heatsink thing? It could be possible that the heatpipe isn't working as well as it should be.

Re: Toshiba C660 IGp chip get really hot.

it losses the gas inside sometimes if there is a leak, may be need to change the heatsink.

As above. Even if it is getting too hot, I seriously doubt this is a motherboard problem. Try replacing the heatsink.

Thanks for the input folks. I didnt know heatsink had gasses inside the copper pipe.

Re: Toshiba C660 IGp chip get really hot.

reflow or replace the igp chip is the only solution i think.

Re: Toshiba C660 IGp chip get really hot.

lol no it is just hot air... sheesh there are no gases ...

What does happen though is that:

A) there is not a even surface on the chip or the heatsink
B) there is build up between the fan output and the copper pipe
C) the solder has become faulty
D) The chip has issues itself

I would check for the build up of crap I have seen this ruin more laptops than anything you will not see it until you remove the fan from the heatsink in many cases it is crazy the amount of stuff I have found on some laptops with bad motherboards it is like someone brushed their pets winter coat off while working on their laptop then what happens is instead of working like a cooler it works as a heater!
