Am I pushing the H50 to far?

[setter]

I tried an h50 on my own i7 today, 4ghz chip, (21x193), 1.2750 vcore, 1.3125 qpi/vtt, it was 5 degrees higher than my current lapped TRUE black, i used the same akasa viper fans that i have on the TRUE.Yes, the H50 takes up a lot less space, but inmho its only an alternative to good air cooling.

Thanks for the tip, I have mine connected to the pwr header and it runs at 1360rpm, so its good to know I can get an extra 147rpm.

Mine seems to change on every boot, but it stays between 1300 - 1500RPM, as long as it's above 1300 it 'should' be working ok.

But saying this why would they say it runs at 1500RPM when a lot of the time it doesn't so it isn't actually running at optimal RPM speeds which decreases the water-flow and impacts cooling, strange.

Its very hot to the touch. I could get you an exact temp if you really wanted me too.

Probably not worth getting out a thermometer for. It was particularly bad phrasing on my part, I was actually wondering if the pump bit is appreciably hotter than the radiator. Thanks for the offer though

Its like its not pulling down hard enough on the cpu, or the pumps not running or there is some heavy restriction between the block/pump and the radiator.

Same thoughts here. Latter two are manufacturing defects, the first could be that or user error. I'm fairly certain it's not user error. Will you rma it?

Well to prove I'm not going crazy I did some tests.

I built a single rad, setup from old bits and bobs I had lying around.

Radiator is an original Waterchill radiator circa 2003 which I am pretty sure is a Black ice pro 120 radiator. Anway its pretty dinged up but should do the job of comparing.

Pump is from the same kit, think its a Hydor, its rattly as hell.

Its all 8/10mm tubing so again nothing radically different from the H50

Block is a XSPC Delta V3 with 1366 adaptor, again not ideal because its designed for 775 chips and has a raised center section that is smaller than the heat spreader on the i7 920.

Fluid is just demineralised with some ptnuke.

I've taken some photos as I went along, might not be interesting to all but might be to some.

How did the single rad loop fair against the H50 biffa?

Here is the H50 in situ. I'm hoping these pics show I didn't install it upside down or anything.

Overclock settings:
Mobo: Asus P6T
CPU i7 920 D0
RAM DDR3 OCZ 12800
191 bus
21 multi
CPU 1.3V
QPI at 1.30625V (next notch up)
DRAM at 1.66V
HT on
Everything else pretty much on auto.

The test bench, I know its on its side, I tried it in every direction with the same results:

Some closeups before removal (should be self explanatory) to show fit:

The backplate up nice and snug:

After removing the pump/block:

TBH it doesn't look like contact was that great. I'll go into it a bit later but I had everything tightened down, the notches lined up with the ring etc.

These are the temps I was getting, just did a quick screen grab late last night before pulling it apart and taking the pics. For interests sake, load was created by running a Folding@home bigadv work unit. I felt a snapshot was good enough as I'd been seeing temps all week > 95°C and this Coretemp screenie is as good as it got. Ambient was about 25°C

H50 idle and under load:

Next, frankensteins loop is born!

Look forward to seeing the difference with the loop built from your old parts.

Come on biffa I want to see frakenloop. Saying that all I have to do is peer through the window of my case. Its like a vipers nest at the moment.

Contact doesnt look great on the H50, I'm assuming you clamped down opposite corners etc

Sorry been a bit offline for a while

Yeah I fitted it three or four times, trying different orientations, every time tightening up as I do with all blocks opposite corners turn at a time.

 

[Biffa]

Heh, frankenloop, not because its ugly but because I built it out of bits I had lying around.

Details: Res & old rattly hydor pump, XSPC Delta V3, Dinged up old rad with Corsair fan from H50

Temps of frankenloop: Idle/Load
