So it looks like the problem with my wife's rig is the Corsair H110i GTX. With rad fans and pump both up to full tilt, it is taking way too long to drop temperatures on the CPU. The other temperatures on the mobo, SSD's, DRAM, etc. are all normal/good.
What I mean by way too long -- when I was using AI Suite to do overclocking stress test runs on my basically identical rig I would set temp limits to stop at and watch the temps. For example setting the upper limit at 75C, and when those load tests would stop running, you could tell the cooling setup was doing its job because even if the temps were pushing the limit during the load test, you would see them RAPIDLY drop (like 15+ degrees C or more) as soon as the test had finished - ie, as soon as you saw the CPU cores "unpeg" the temps would rapidly drop.
Her machine, it is taking on the order of minutes to get her CPU temp down from 50C down to 40C'ish. It was not like that before but it definitely is now -- even with the Corsair Link software reporting 3120-3180 pump RPM's and fans being cranked up. I don't think the pump is actually pumping, or something else major is wrong. Others have similar symptoms with these units and series.
So I don't think the issue is the mobo, CPU, or thermal compound job anymore. I have pulled, completely cleaned (with Artic Silver 2-step thermal surface cleaner -- great stuff) and re-stuck her cooling block 3 times now. I *KNOW* I did it right the last time (and felt really good about the previous 2 times also). It's just the H110i GTX cooling setup.
I didn't want to believe it was the H110i GTX because the RPM's from the pump looked right - but it's pretty obvious now, looking at how poorly (slowly) it can drop the temperature on hers.
We got these just over a year ago when I built our rigs. I was hesitant to go with an all-in-one setup, knowing people have issues/complaints etc. and they are usually not the best of any part -- radiator, pump, waterblock, etc. But they're supposed to be easy and maintenance free. blah blah blah. I didn't want to spend months building our rigs..
Anyway, now I'm looking for some inspiration on a custom CPU loop in HAF-X cases. ie, ways to mount a reservoir, rad for the CPU, etc. and fans.
If I'd known I would end up here (maybe I should have known, heh) I would bought different cases. Dunno what case this is in this post on another forum
but it is a nice one.... (custom work is awesome too but I mean the case)
It is a bugger to get to anything in the pharaoh rig but at least if/when a pump dies I can just replace it and not have to mess with the waterblocks.Edited by pharaohspaw - 9/26/16 at 5:17pm
