It's springtime here and the temps of the CPU case are ~52° (Q6600@2.7). I think about to buy a water cooling system and overclocking at 3GHz. Anybody know a good quiete system? I think about a passiv system with a hugh flat radiator that can be mounted at the PC case side or a separte system like this:

OK, today it's not so hot like the days befor, but a good trick to get lower temps is to set the Vcore at lowest possible value. I jump from 1.275V to 1.185V (Speedfan meassure 1.12V) and the full load temp is less than 40° @2.7GHz and lowest fan speed.
Idle CPU case temp 25° at 21° room temp. I wonder me, the Speedfan system temp is 38°. What is this system temp?

I got the Vcore hint at this german forum:

If the Vcore is to low, than I get a message at PC BIOS startup and I can jump to the BIOS settings to correct the to low value, so no risk at all, only fun, if the temps are lower.

hi Micha,

if you don't get a bios message or you can load windows, it doesn't mean that your sys runs stable. you have to test under full load. the vcore normaly drops 0.05-0.15v under full load (depends on the board). you should run orthos prime to see if the sys runs errorless.

btw: this e6600@1.01v is a v e r y good one - in his sig this guy states that he got it to 4GHz... this isn't normal for all e6600 - or q6600s

and an interesting test of a new integrated peltier cooler ...would be interesting to know how many watts it needs for the cooling.

Thanks for the infos. I found this for the peltier cooler:

If I understand right, it need 100W at full load cooling.

Last I got some system crashes and I lower my CPU speed a little. I will fine tune it the next days. At the moment I run at 2.79GHz at 40°C full load. So, I need no special cooler.

Peltiers will be more suitable as chip manufacturers decrease the thermal output of their products. If a peltier element's design doesn't exceed the output of a chip, it will use its energy to add heat to the system.

Yes, it's realy disadvantage to consume more energy. From a technical view only, it's an advantage to get a higher difference between environment temp and hot elements. Cool down a 42° CPU in a 30° room temp is not so easy, but cooling a hot peltier cooler is easier.

I'm happy, that I can get lower temps per fine tune of the CPU voltage only. 20% overclocking and lower temps without new cooling device, thats great. My QuadCore system use approx. 220W at the power supply with slow, "noiseless" AIR cooling.
