I thought that just adding a cheaper second GPU will make my rig last longer before that all consuming need for a brand new build takes over my soul! I really want to wait till the next generation of CPU's and GPU's come out, so that I have a really good jump in preformance.
So, I added the secondhand GTX280 to my gaming rig, and it started melting the polar icecaps...
I very nearly pooped myself during that test run!!
So I changed the drivers which had no effect. I then added a few more 120mm fans inside the case, and I now use EVGA Precision to speed up the fans at lower temperatures to keep them cooler for longer.
This little bit of work has produced a fantastic result...
All I need to do now is remove the heatsinks, clean them, and reapply thermal past/pads. I'll get round to doing this soon.
