So it's a little off topic. There's more info in the OP than cpu temps.
Where did I say it had anything to do with cpu temps? My 1 liner was a suggestion and I thought a good one, even if some don't agree.
The fan reconfiguration will help. And upgraded cooler.
The FX liquid cooler should be about like an H70 and made by the same maker. Nice customer option imo.
Coolmax is notorious for not living up to their specs. They only have about 3 or 4 units that can even barely live up to thier 80% efficiency label alone. They are a Co. that will aquire already built very cheap units, and maybe like ZX 700 not even have an on/off switch, from whoever builder and put "Coolmax" on them, and sell them.
So, I still wouldn't invest more money into the rig w/o upgrading the ps. Others can do as they wish.
Edit: That one does have a switch.
