6970 freezing after 84c on water? - Page 2

post #11 of 18
You said you got the plastic off the thermal pads peeled off, but what about over the gpu area? Those temps are terrible for water.... but even at that it shouldn't shut off at 84c. Can you see adequate flow in your resivor and is it possible the threads on barbs maybe go too far in blocking flow?

(check those pad thicknesses)

I think "pea sized" is not good for GPU. Others suggest thin covered layer of TIM on the GPU.

Also, the radiator listed...is that the one with the integrated 355 pump? If so, I'd say you might be a little low on pumping power. The radiator should be able to handle the amount of power it has to dissipate, but the video card is getting hot water after the CPU. Maybe get a small 1x120 radiator to trim some heat off between the CPU and GPU? It worked for me pretty well.
Yea it's the same pump, but looking in the res it sure seems like the flow/pressure is ok. I cant see a difference compared to when it was cpu only.

This is what I really dont want to do lol

Air was ~52c idle / 76 max. Fans are at 1700 rpms

I did the whole criss cross thing that EK said to use. I might have to stop by Microcenter and pick something other than my AS5. I like the light idea. I ll do that for sure tonight.

Yes all the plastic I saw has been taken off. The res seems like it's getting great flow so I really don;t think it's that. I didnt use the spacers for the barbs. It didnt look like I need tem. these are my barbs Yes all the plastic I saw has been taken off. The res seems like it's getting great flow so I really don;t think it's that.

Just retim it

Making a big deal out of as5.

Dont worry. If u watercool a gpu, it's temps are already pretty damn low. No need to worry about curing.

What's the point of curing if your max on the gpu is going to be like 45c.

40c-45c isnt that big of a deal when u wc/mess with cure times.

Just reinstall the block.

Can you please upload some pictures of your loop? Many times extremely high temperatures like these are caused by a fundamental issue with the loop itself.

Are the inlet and outlet tubes on different block holes?

ALL IS WELL!! It seems like it just wasn't tight enough. I came home, tighten all the screws a little more and BAM! Temps are great. Thank goodness I didnt have to take it apart. Now I have seen diferent temps at diferent resolutions which is to be expected. Here is what I have seen so far:

Ambient is ~25c

Resolution Idle(c) Max(c)
@ 1680x1050 ~30 ~43 Single 22"

@ 1980x1200 ~34 ~46 Single 25.5"

@ 5884x1200 ~39 ~51 3x 25.5" Eyefinity w/ bezel comp

What do you guys think? Maybe it could be a little better but I am very satisfied with the investment. Below are some pics of the loop and my setup. Yes I know I have to pick up some the cabling
