i just got a VF900, it was on sale for $30 so i went for it. my temps went from 43C/59C to 36C/50C(660 core clock). it is fairly cold where my PC is to begin with

also for the RAM heatsinks i put some AS5 in the middle and small dots of superglue on the corners. it will hold fine but when you need to take them off it only takes a mild amount of twisting to get them off

i am pretty sure if i cleaned up the bottom of my case a bit it would be lower.

summer is the real test i am waiting for right now, if it doesn't work then i will sell it to my cousin for his card and buy a VF1000
