Howdy guys, had a thread related to this a few months ago and finally got the correct mounting hardware for my water cooler today, but couldn't ever get idle temps below 44C, and load temps were absolutely terrible.
I spent about 3 1/2 hours crouched over my tower, disassembling and reassembling the cooling system trying to get it to work properly. I had the radiator mounted to one of the intake fans with both fans pointed in the right direction (the second time...) and the hoses oriented above the radiator. I pulled the block off I don't know how many times, applied various amounts of thermal paste, and cleaned and recleaned the surfaces of the block and cpu with no discernible change.
I know the pump is working because I can hear it pumping the water, I can feel it vibrating if I put a screwdriver and my ear up to it, one hose is cooler than the other while running, and I get a readout of 1500-1550 rpms for cpu fan in the BIOS.
When it boots up, temps start out about 44-45C, and very slowly start crawling towards 50C. If I leave it sitting for about 20 minutes, it'll get up to 50C. I took the CPU off to clean off some excess paste that had gotten on it when I tried more than a pea size, and after applying about a BB's size to a pea size of paste, I had temps start out at 39C when I loaded it up, but they quickly jumped to 45C and made the crawl to 50C. I figured that was because I pulled the CPU off which allowed it to cool away from the mobo. I even tried throwing 2 rubber washers on it and temps changed maybe by 2C, but still made the crawl. Load in all of the cases got above the CPU max temp, and even got to 86C at one point.
I'm quite stumped, everything I know to check is checked and double checked before turning this thing on, everything is hooked to where it should be (link usb to JUSB2, fan to CPU fan, no other cables), no increase or decrease in paste amount has made a difference, I've even tried mounting the block a few different ways to no avail. The pump is running, the paste is the right amount, the hardware is right, it's only pulling in new, cool air, the surfaces are smooth, the computer can see and operate the pump, and everything is where it should be, or so I believe. I've looked at the install instructions from the manual online (https://www.corsair.com/corsairmedia/sys_master/productcontent/Hydro_Series_H80i_GT_QSG.pdf) and there aren't any steps I skipped. I even put my little gravity i2 back on to see if I mucked something up, and the temps on it are better now with the reapplied paste - I haven't seen 70C at a full load test, and it idles 36-38C. Everything is at stock levels for power. This was pulled off a gaming tower that had a mobo failure, the cooler was working flawlessly before that. All tests are on an i7-2600 done open case.
Am I just dumb? What else am I missing? My only other thought would be that maybe there's air in the lines or pump as those can make things get real hot, but I've no clue how to check that, bleed this or even what I'd use to refill it.
