Max CPU Voltage On Water Cooling ?

post #1 of 5
Thread Starter 
I was wondering would something like a 1.53 CPU voltage be ok for a 24 hour 7 days a week use? I am only water cooling my cpu which is a i7 990x with a RX360 rad in push/pull config with a Koolance 370 waterblock. Also what would be safe temps under full load?

I'm no expert, but that sounds a little high for everyday use. I would probably try and stay under 1.5V. The cpu temps may be fine and it may not degrade the chip that much, but it may take a toll on the mobo VRMs, etc. I've got the RX360 myself, and I'm wary of going over 1.47 for everyday use. For benchmarking however, I would just keep a close watch on my temps and worry a little less about the Voltage. To each their own.

From my understanding.. anything over 1.4 runs an exponential high risk of permanent cpu damage.

Yes but what if say you have a cpu voltage of 1.40 and the temps under FULL LOAD are reaching max 63c? isn't that good? I don't see how that can damage the cpu since the load temps pretty good

The thing is that temperature isn't the only thing that can degrade a chip. Too much voltage can have a detrimental effect as well as it forces more current through a chip that just can't handle it. But I don't think that under water you'd see any detrimental effects until at least 1.45V.

Edit: Voltages can be a very touchy subject, so you may want to read the safe voltages section in the Sandy Stable Club page:
