First time WC, for the moment on stock settings i'm at 18 idle and 28 with Prime 95 :)

Still have a little to do on the cable management side, and I'll be aiming for 4.5ghz this weekend ;)

18 idle? A little cold in your house?

20/21C (68/70F) I find that quite alright, any warmer and I can't sleep.

You're not going to be sub-ambient with water cooling unless you have some kind of chiller. I would seriously question the accuracy of that reading.

Those are core temps (ive been told they were the most important) the cpu temps are 10 higher.
And temp reading in the house is perhaps not so accurate?

Water cooling uses the temperature differential with the ambient air (which is normally cooler) to move heat out of the system. If your ambient temps were actually higher then the differential would be flipped and the ambient air would be heating your computer. So the laws of physics dictate that none of your readings for any component or probe can be sub-ambient unless you bring phase change or TEC into the equation.

18c is impossible with ambient at 20+c
28c sounds a little more in line.

Nice setup man! :)

Iv'e put a thermometer near the PC and my readings are as follows : Ambient temperature - 18, core temperature - 18, cpu temperature 28 (taken with AI Suite and HWMonitor, PC on idle with cool n quiet, syock speeds)

How can my core temps be 10 lower than the cpu temps?

Looking very good! I too wonder why the core temps usually are between 8-10 degrees lower than the cpu socket temp? Looking forward to seeing your temps when you shoot for 4.5Ghz :)

i like it good job!!!!

I have to agree with xeromist, something wrong with those temps! You can not have lower temps in your pc than the ambient... Not even the same core temps as the ambient - it would mean that the cores are not producing any heat. I think the sensors on your mobo are playing you...

Did you run the AI Suite and HWMonitor in the same time? There were reported issues running them like that - causing wrong value readings or something.

Regarding the difference between the core temps and cpu temp in HWMonitor, there were discussions about that too. Because of the sensor setup, cpu temp will be always higher, but sometimes will be rocket high. I had this issue with my R3E before, and I saw in other's postings too.

So, what could you do? First, run only AI Suite or HWMonitor at one time. You could try touching the water block on the cpu, specially under load, should feel cold (like any other metallic thing in your house - ex: side of the refrigerator) at those temps (your body temp is around 37C, so anything lower than that is cold). If you feel it warmer, then your sensors are wrong - that case be careful with OC! Also, be careful with touching things inside your case, touch only the water block, not some mobo components.

Of course, the best would be a non-contact thermometer...

Thats very logical, and the first time I have heard anyone say that, next time I have the side off, I will stick my finger on the water block to see what the temp is like.

Thanks Zka

Looking good after the cable management even better.:cool:
