i5 3570 temps on water normal?

post #1 of 2
Thread Starter 
First of all thanks to the peeps who chime in. I have recently installed watercooling on my father-in-laws rig which was also built by me just a few months ago. The specs of the systems is as follows.

CPU: i5 3570 Stock
Motherboard: Asus P8H77-I
OS Drive: Crucial M4 128GB
GPU: iGPU
Case: Inwin 643 mini-itx

Water cooling Loop
Pump/Water block: Swiftech Apogee Drive 2
Radiator: Black Ice Dual 80mm with dual 80mm noiseblockers 2500 rpm
Tubing: 3/8. 1/2

Ok before the crowd goes nuts on this ridiculous setup, I know its dumb he doesn't game and stuff and uses integrated gpu why is he on water in the first place. The man is anal about his mini itx system not getting enough airflow and I just wanna get it done and have him off my back biggrin.gif

So I should state I have done all the normal routine stuff and I have been doing water cooling for a few years as well.

Re-seat Cpu with thermal paste IC7
Ensure all air bubbles are cleared

I have also considered that dual 80mm rad is 12800m square which is comparable to a single 120mm rad which has 14400mm square of rads. Also airflow should not be a concern as the rad is externally mounted and I have ensure it has proper airflow so that this would not be a factor in my test. In case fan static pressure was a cause, I have tried placing my Scythe GT-30 at 4250 rpm on the rad but the temp wouldn't budge. I have also varied the pwm mcp35x from 1200 rpm-4500rpm in case the flow was too much.( I know martins had some tests that described optimum flow)

Also I have ran prime95 overnight and the load temps are at 50c. Air coming out of the rad is cool lol. I do think that could be signs of an optimum water cooling system?

Alright so now all the doubts been cleared, this is the concern, the temps are idling at 35 degrees. Ambient air temp is at 29c. So Delta T would be in the 0-5 c range which is good but the issue here is I have done a search on the net and people are getting these temps on stock cooler. So it kind of makes water cooling a joke.( yes I know what you expect from a system without an oc)

I have ever gotten my idle temps for an i5 650 from 35c for air cooling down to 29c with ambient at 28c when I switched to water. So I was thinking if its possible to get the i5 3570 idle temp just say 2 degree away from ambient temp. I also do understand that temps should be benefiting from load and not idle temps. In any case just trying my luck not saying this is a problem but I thought I put it out for discussion been spending the last 48 hours cracking my head on this one.

There is a physical limit on how low idle temps can go, and no one gets water cooling for idle temps. I'm not sure why you'd even care, to be honest. The CPU is putting out so little power at idle that you'd probably get those temps with just a passive heatsink.
