What is the release date for the H320? in early April?

With us moving into the new production facility, I really can't say when those will be released. I'll keep you posted though.

Bryan, how exactly is this done in the factory? could we just attach a hand pump (like those found for brake bleeding) to the end of the loop or tube after the pump and apply a vacuum?

No, you really can't do it that way because these radiators have a specific pressure tolerance. I can't remember what it is off of the top of my head right now, but I'll find out when I get in on Monday. If you exceed that tolerance then you risk damaging the radiator.

I troubleshooted this a bit with BramSLI1 and appreciate his kind help on this. Rare to see this kind of private customer service these days. thumb.gif I always like to troubleshoot the best I can myself before taking any final conclusions, I've worked in RMA dept myself for nearly 4 years in the past. smile.gif

Now I have tried to connect the pump directly into the MB and also through the bundled panel with and without the cpu fan header connection but the situation seems to be always the same: the pump works from a cold start for a while and then it goes to 0 rpm, goes back on for a while and then nothing, my computer shuts down due to thermal shutdown. I believe I have now ruled out the fan headers, and I don't see much left to do. I will do an RMA through my retailer in Finland, that's just how things work around here, unless they tell me otherwise.

Here's a screenshot, taken just before a shutdown when I had the pump directly connected to MB. Check CPUFANIN.



And hey, my CPU is still alive. Hopefully not degraded... wink.gif

How about inadequate power supply?

I think if the PSU couldnt handle 6w of 12v power, there would be much larger concerns here...

So I read on FrozenCPU and it says the H220 is 29mm thick, is this true even with the fans?

You are probably lucky to be pushing .5GPM with that block as a guess, but I'm not sure what the H220 pump curve is producing. 4lpm is pretty close to 1gpm.

Hearing H220 pump head should be similar (per RPM) as the 35x at the same rpm. Gussing that is 1-2m max which would put you under the 2LPM or less than .5GPM mark which is bleeding trouble flow rates. Performance should still be good, but I'm not surprised you had bleeding problems. The older 80 is like stinging a dozen normal gpu blocks in there.
I get no temp difference between pump at 20% 1500RPM and max speed. I have the PWM set to 20% @ 40C on the CPU fan header, so during game use, it probably gets to 30-35% at most.

See any issues with running it daily like that, or should I look in to getting the MCW-82 housing? Id really rather not have to disassemble and refill again. Now that the bleeding is done, if there isn't any negative point to a lower flow rate, then Ill keep it as is.

No, should work well as long as you got it bled out. MCW80s dense micro pins is probably a very good low flow rate performer as most high restriction blocks are (your results seem to confirm that too). Just makes bleeding difficult is all. As long as you got the big pockets removed and the pump is quiet, I'd call it good..thumb.gif

Your temps look very good so I wouldn't mess with it.

With the fans attached it's 53.7mm thick. That's with the fans on the same side of the radiator as the fill port.

Anyone knows if this will fit a Corsair 600T with Sabertooth Z77 board?
