Hi there, I built myself a nice custom system back in 2013 with a i7 3930K processor, the Corsair H80i Hydro Series Liquid Cooler to keep it running (Samsung SSD for OS and 32GB of Ram (1/2 max) for a Intel DX79SI Motherboard) .

Well just recently (The past week) I noticed my system was acting like it was hiccuping lagging up and even seeming to have a hard time just running web browsing and older games like Civilization III.

I did all the normal things, defrag, disk cleanup, registry cleanup all the file moving and deleting that might be causing it to bog down, ran virus checker (Vipre). None of it seemed to Fix the issue.

I didn't think there was any problem with the hardware, most of the hardware diagnostics came back okay, but on a whim I downloaded Corsair Link 4 from their website to check the temperatures and noticed that my processor cores (1-6) were listed as being in the 90 degree range. the H80i also registered in the 87 to 89 degree range. Certain that was far too high I checked and saw it should be 30-40 degrees cooler.

I maxed out the Fan speeds, which didn't fix the problem. Took the H80i out of the case, Shook it a bit (it sloshes so it still has coolant in it) Cleaned the fans and the radiator, Added an additional exhaust fan (one I had spare) in case the case itself was too hot, plugged it all back in and Checked again and the Processor is running still in the 88-90 degree range, though the Liquid Cooler is listed as running at 84 Degrees so it is much cooler after having been cleaned. The fact that the Liquid Cooler and processor are listed as running as near the same temperature as each other leads me to believe the Thermal Paste I applied at installation is still working correctly otherwise the Radiator would be much cooler than the CPU (At least I believe it would be).

I've never overclocked the processor (never needed to) it can't be the case itself, because the GT630 Graphics Card is listed as running 41 Degrees, And all the Hard Drives I have installed are in the 25-30 Degree range. The Processor is registering only a 10-18% load so I'm not certain what could be causing it to run this hot all of a sudden.

Any ideas if this may be what is causing my hiccuping lag issues, and if so What may be causing it to Run so hot all of a sudden. I wish I could tell you what temp it ran at before but naturally until I started having issues I didn't see any reason to Run a temperature recording program if I wasn't going to overclock. I'd like to avoid taking it into the Shop if I can help it (No real local repair shops to visit) Thank you all in advance.

System information follows
Motherboard: Intel DX79SI
Processor: Intel Core i7 3930K Running Windows 7 Professional
CPU Cooler: Corsair Hydro Series H80i (Fans pulling air inwards over radiator as suggested)
4 Intake Fans in the Front of the Case 2 in front of and 2 behind hard drives mounted
2 Exhaust Fans, one top one side.
 
Sounds to me like your pump died. Pumps in AiO coolers are notorious for dying young, manufacturers try to keep the bill of materials low and so they're usually cheap junk. If it is indeed dead, you could try RMA'ing it, otherwise you need to replace your entire cooler.

If you do need a replacement, the H80i is outperformed by inexpensive air coolers. I wouldn't recommend another AiO to replace it with.
 
Hi drronin :) I'm a little concerned with your description and I think your CPU has been throttling due to heat.

Quote: Took the H80i out of the case, Shook it a bit (it sloshes so it still has coolant in it)

It's a sealed unit and should not slosh as you describe as that means it has a leak. The unit should be full. Very often in cases like this an air bubble can get caught in the pump and the unit will not cool efficiently. I would check this out. Do not continue to run your system if CPU is in the 88-90C range as that will degrade the chip fairly quickly.

Well the Corsair link program states the Pump is operating with variable RPM levels, and if the pump isn't running, would the temperature listing for the H80i be as close to the processor temp as it is? The same reason I was certain the thermal paste was still good is because if the coolant isn't circulating then the heat would take longer to reach the radiator by normal conduction.

Naturally the one spare part I don't have laying around is a spare heat sink for the processor and thermal paste to swap out and see if it does any better, But I'll have to check the warranty information on the Cooler I saved in my paperwork (I think 3 years later I may be outside the normal returns time frame though with the store I purchased it at originally and would have to deal with Corsair directly). I was hopeful there might be something I was overlooking before getting into replacing the entire heat sink system. But I'll keep the recommendation about swapping to an air cooler in mind if it comes to that.

Sorry about the concern on that, When I took it out of the box at the onset it had the same amount of "slosh" of fluid in the radiator when I'd move it about to install the fans and put it in the case. I should have been a bit more specific that it was making the same noise as before when moved or shaken, which if it was making a different one (like a "Glug-glug" as the fluid went across the radiator, or none at all) to me would indicate that it had lost vast amounts of fluid from a leak. I was merely trying to convey that it sounded like it had the same level it had back when first installed.

And for the time being I'm using my old spare laptop for general online work since before posting here my own attempts at a fix didn't seem to correct the problem. I do appreciate the concern about my poor chip's survival though.
