Gateway 6860FX need tips on GPU (heatsinks & fans)

post #1 of 5
Thread Starter 
I started having an overheat issue with my 6860FX and I plan to dig into the machine this coming weekend.

I've found a few guides here and other places on how to take these apart so I'm not too worried on that, but I could use some "pro tips" on ensuring I've done everything possible before I send it off for warranty work.

Long story short my GPU is overheating to the point of instant computer shutdown/power off. I can be in Windows without any issues, but within 15min or so of playing a game like Borderlands, Half-Life, Portal (the first one) the computer will instantly power off. Before this happens the air coming from the GPU vent is almost too hot to touch. I can of course avoid this by raising my laptop up a bit and opening a window and letting cool air into the room (never needed to do this before of course)... doing this allows me to game forever without any problems.

I've never overclocked the GPU or CPU. Since having this machine for about 3 years I've only upgraded the HDDs, BIOS and OS. Previous to this overheat problem the computer has been a dream.


The plan is to double check the "TIMs" (sorry, not sure what it stands for, but I assume it's the thermal pads?) and replace them with some new thermal paste... maybe AC5?? Of course do the usual dust clean up as well.

I guess I'm wondering if there are any "upgrade" fans or heatsinks that I can purchase and install or if there are any tips for cleaning the copper so that it can conduct heat better.

Really, any info that can help me reduce the heat and stop this issue from happening, because if this fails it's warranty work time (through Best Buy extended warranty) and I'd rather not resort to that yet since I'm concerned the laptop will return in worse shape and start me down a path of crap that lasts 6 months.

I thought I'd add some info...

I downloaded GPU-Z and logged the info into a text file. I then loaded up borderlands and started playing. Here’s a quick break down of the log

Temp Pre-Game at Windows Desktop = ~50c

Started Borderlands @ 06:57:35

Temp @ 06:57:40 = 61c
Temp @ 06:59:11 = 71c
Temp @ 07:01:57 = 81c
Temp @ 07:07:23 = 91c
Temp @ 07:14:08 = 101c
Temp bounces a little between 100c and 101c from that point on until an instant off at 07:14:29

I'm not sure of the threshold, but I suspect it reached 102c when it powered off.

....that's not good.

Get some compressed air and clear out any dust.

I've owned the same lappy so I know what you're going through.

The good news is that it takes 2 minutes to remove the heatsink for the CPU and GPU. Gateway makes it very easy... remove the 6 screws holding the cover on the bottom. i think 4 screws for the actual heatsink and thats it. remove all thermalpaste/pads from the heatsink and chips. Clean fan out. Add new thermal paste and replace heatsink.

I could probably do all that in less than 5 minutes so its not a big scary job by any means. Just take your time and follow directions.

Good luck!

already blew the dust out, didn't help. Also, the CPU and Chipset heat sinks are easy and are what you describe.... but to get to the GPU and heatsink it requires taking pretty much the whole computer apart. That's why I'm looking for any thermal paste, heatsink and GPU fan tips/upgrades. I'd rather only do this once a good while.

I should note too, that I own a little air compressor that I use for blowing the dust out of computers. Saves me a ton on air cans, plus has way more pressure than really needed so I "really" blew the dust out... and about a mile down the road to boot, lol.
