5770 shutting down with liquid cooling, but NOT overheating?

Postby SC2n00b » Sat Dec 17, 2011 11:00 pm

I had a GPU-210 installed on a Sapphire 5770 video card, working perfectly for the first week, but then the screen would go black (instantly and without visual artifacts prior) and the card had the D4000 red LED lit up.

- using CPUID Hardware Monitor -
with Koolance system:
85-90F idle
100-104 during gameplay (starcraft 2)

with stock air cooler:
95-100F idle
solid 150F during gameplay (starcraft 2)

I thought I had a bad card, so I took it out and used the onboard video on my processor, but thought I'd try it with the stock cooler again. Sure enough, it works perfectly with the stock cooler and much warmer temperatures.

I guess my question is: Does this card need to have a fan plugged into its header once it begins going over 100 F? Or perhaps is it the rest of the card getting warm and that's enough to shut itself down? The stock cooler does provide some airflow over the rest of the card, while the Koolance water block obviously only cools the GPU itself (I don't have much for air flow in the case near the GPU).

Hopefully someone can help me with this, because I really hate the noise of the stock cooler and would love to bolt my Koolance block on it once again. (and yes, I did check to see if the block was tight and I applied thermal paste correctly, how else could I get such low temperatures with the liquid cooling? :)

Sounds like you have it on just the GPU and not the VReg which I believe is that small chip on the card. Try looking for the 5770 block which would be a better fit but before you do that when you start the PC look at your VReg temp and see where its at cause that will cause the system to shut down.

You can find an app which will show it for your card: http://www.techpowerup.com/downloads/20 ... v0.5.6.htm

That app will be a great place to start.

1- What else is in the loop with the GPU?

2- I'm with Ace on this one you VReg temperatures are probably the issue here. They get HOT on any video card.

Wow thanks for the responses guys! I didn't think about the voltage regulators, but I figured I would mount a nice big 140mm intake fan right above (HTPC style case) the video card area to take care of any surrounding dead air around the card for the RAM and Vreg. Do you think that would be enough? That's pretty much all the stock fan is doing. I'm going for a quiet setup, and that fan won't make much noise, much less than the stock cooler that came with that Sapphire card anyway...

I'd love to hear your input on this idea. That fan will also help air move around the hard drives next to the board as well as the entire motherboard itself. Like I said, it's a home theater mATX case so there's not much room in there!

Oh, and Izerous, the only other thing in the loop is my little i3 processor, which produces much less heat than that 5770. Getting great temperatures with the Koolance install, just think I had too much dead air in the case since there were no fans anymore except on the radiator...

Definitely try to find a waterblock made for your specific video card. Will be the best way to go.

Since the thread got bumped just wanted to check in to see how this progressed, was the fan sufficient to help or are you still having some issues.
