Overheating on Liquid Cooling?

AManWithPlan · January 10, 2018

Alright gents, this is is a doozy. I have a fully liquid cooled setup using AIO or included coolers. Two 980 TIs from EVGA that have liquid coolers as part of the card (no aftermarket). And my CPU has a Corsair H100i GTX. My temps are what I would call, excellent, but during certain games (namely Heroes of the Storm) I can experience one hell of a hard crash.

I thought one of my cards were going so I swapped the two TI's in their slots to switch the master/slave, and got the same crash shortly after. I even had a hard crash just reloading the computer and using Chrome within minutes of a restart.

However, once I left my side panel off, and temperatures fell an additional 5C or so; I haven't had a SINGLE hard crash since (about 1 week) in any title. How on Earth?

My suspicion is a motherboard component that isn't jiving with case temps, but I have so, so many fans in that beast (3 intake, 3 outtake; outtakes are double layered meaning 2 fans each).

Let me know what you're thinking. Any time I track GPU or CPU temps, I am well within operating.

I mean I bought an AIO watercooler a week ago from amazon and it didn't even have water (And it nearly killed my cpu. Thanks Corsair) in it so I'd be suspicious of the water cooler

Honestly, it's probably just one of many issues with SLI.

It really isn't worth doing anymore.

You're not going to get twice the performance in most games like you'd think and often it'll cause games to completely crash. Developers just aren't optimizing for it anymore.

I can't explain why it started working with the panel off though.

I personally think that was just dumb luck, but I could be wrong.

Hmm... one idea.. if this happens again.. try removing and reseating your SLI bridge. Maybe when you took the side panel off, it got bumped or something and started working right again. That's a theory anyways,

If your temps are fine, I doubt it has anything to do with that.

I'll try fiddling with the SLI bridge, but the "solution" seems to be case panel is off (for now).

I doubt anything is wrong with the water coolers, I would see the temps rise and I don't in HWMonitor.

Yea, if your temperatures are fine, it can't be an airflow issue so we gotta think what could taking that panel off also effect and the first thing that comes to mind for me is that SLI bridge. Closest thing to bump and something that could definitely cause what you're experiencing.
