Another cooling mod

Gateway Laptop Discussion Forum - forum.notebookreview.com
I have to start off by stating attempt these at your own risk. I am only showing what I've done so others can benefit from my experience doing these mods. I'll cover my first mod then get to the additional one in a seperate post under the same thread. This is for those who hadn't seend what I had done before.

I run the Q9200 and over clock it as well. I had noticed, and it was confirmed by others, that with Prime95 and even a Q9000 the cpu throttled at stock clocks and voltage. I knew I could not stop this without undervolting but I had to try and at least get it too take longer to heat up. My Idea here was two fold. First increase thermal mass and second to try and cool the heat pipe so that actual liquid returned to the pad in contact with the die.

I purchased a mini GPU heatsink and fan. I then used AS5 GPU adhesive TIM to glue the heatsink minus the fan to the CPU heatsink over the CPU die area. Since the new assembly was too tall I also had to cut out an area in the cover for the new copper HS. This alowed also for some additional air to get to it as well.

With the mod completed at 2.4 GHz and stock Vcore I could run Prime95 for 5 minutes without throttling. Before I was lucky to get slightly over 3 minutes without throttling. Once reassembled I could run Prime95 with TS installed at 2.93 GHz and without overheat for extended periods but it was not something I would leave alone. 2.66 GHz though now was 100% stable and with Prime95 stayed at 85C or under.

Now this mod may have added some weight but did nothing for air flow or noise. The CPU fan just as always seemed anemic at best, not even on at worst. Something I had just accepted until recently.
