Water temp is 50?! That's hot! I'm not sure the tubing is meant to deal with that is it?

Now you know why he sold it, did you post a picture of the IHS as I've not seen one?
Temps are fine considering you fan speeds, although at that low RPM they're not going to be pushing a lot air through a radiator, I would by another set of 5 fans for push/pull as that should provide a nice increase in cooling performance.

Water temp is way too high. If I remember right, most tubing is only rated to 60 degrees. My cpu doesn't even hit 50 degrees while gaming!!
The tubing does get quite flexible when it is at that temperature.
His on the left - mine on the right. Quality is a little potato as I do not have a good camera to hand.
I have a couple of spare 120mm's around that I can add to the rads and see if they make a difference. Will have to move stuff around though as there is no room on the other sides of the rads.
It does seem quite hot so I am going to do some tests. Case panels off at 1200rpm fan speeds. Case panels on at 1200rpm. Case panels off at current speeds. All will be done using BF3 as that stresses the GPU to 100% and CPU usages hovers around 80-90%.
I also have the pump (Laiing D5) set to the lowest speed as I did some testing and found it made no difference. Is this generally found to be correct? I ask as it is quite a chore to change pump speeds.

The guy I bought it off has offered to take the 3570K back. How much do you guys think I could sell a Maximus V Gene and a 1x8GB 1600Mhz stick of ram for? He has offered to take it all back or just refund the CPU.

About £80-90 for the board providing it has I/O sheild, £30'ish for the RAM.
H440 is known for poor airflow.
I usually run my GTs at ~1100rpm +/- 10% when gaming, so I would expect higher than usual temperatures with that setup.
50C water temperature seems too high though. Like others have said, most tubing is only rated up to 60C, and too much heat can cause it to warp and leak.

My setup
You shouldn't be seeing temps that high tbh, I haven't read through the whole thread but what fans are you using? Also maybe try another cpu block? I noticed quite a jump from a koolance 370si waterblock to a Bitspower cpu summit block.
Using 3 Noctua NF-P12s at the front and 2 of the stock NZXT fans in the roof. 1 Noctua NF-P14 as exhaust. All the radiators are Alphacool ST30s.
I have 1 Noctua NF-F12 sitting on my old D14. I will replace one of the stock NZXT fans and see if it makes a noticeable difference.
I am genuinely fine with CPU running at 70C, so I won't replace the block.

Lack of air flow is you're biggest problem, not the CPU or the block, those Noctua fans are **** poor for water cooling.

Uhm, I've always had the impression that they're quite good, unless I'm thinking of a different model
martinsliqudlab has fan testing equipment that review sites simply don't have access to and on his testing they're no better then a £4 Arctic Cooling F12 when it comes to performance on radiators.

Just for reference... I've been benching the rig in my sig this evening on 1x 240mm rad because the other has just sprung a leak...
Max CPU temp 50*C
Max GPU temp 39*C
Max CPU temp 50*C
Max GPU temp 39*C
The static pressure rating on the NF-F12s is 2.61 mmH2O which is pretty good.
NF-P12 is 1.68 mmH2O and Scythe GT 1850s are around 2.9~ mmH2O, to give a frame of reference.
Would recommend swapping in the F12 if possible. Couldn't you just up the RPM on your existing fans too? The static pressure ratings are at max RPM, so they're going to fall off at lower speeds too.

Manufacturer static pressure rating mean bugger all my friend..

Have a read of some of his fan tests... Noctua's are no where near as good as people make them out to be..... Martin has test equipment review sites can only dream of and his findings and reviews are regarded as the best by the guys over at extremesystems.

The P12s aren't great. The NF-F12s are one of the most well renowned fans around for cases and radiators.
Surely these numbers aren't right? Unless you aren't stressing the entire system or your 240mm radiator is 80mm thick with deltas in push pull whilst outside at night?
The NF-F12 has been installed in place of one of the stock NZXT fans. I have also upped the fan speeds to 900rpm across the board. What I thought was my fan making noise was the extractor fan for the cooker.

3dMark, superPi and prime95.
All at stock clocks for now until I get this rad fixed/replaced.
The rad is 60mm thick with 2 SP120's on it turned right down on the fan controller.
