Unsure if im in the correct thread, but i want to know whether its just me being impatient or that my system isnt working properly. Basically, i just purchased a custom water cooling loop for my R9 290X, im using a XSPC 290x water block, a XSPC 170 Res/pump combo, and a XSPC EX 3X 120mm fan radiator. I just installed it tonight and have let the pump run its leak test for around 12 hours now. (I got a bit impatient waiting for the 24 hour leak test). Plugged everything in, and started my system, and it ran all good, using MSI Afterburner to monitor temps on my GPU as always, and it was idling lower than it was when i was using the aftermarket air cooler i had on the card before, 37*C with water cooled and 41*C aircooled. But after running 3D Mark on fire strike, the temp jumped 90*C within seconds, leaving the side panel off, i put my hand on the tubing leaving the gpu block, and it didn't feel warm at all, i alt+F4'ed it and the temp dropped straight back down to 37*C just as fast as it rose, faster than the air cooler, as the air cooler peaks at 70*C on the same benchmark test.
Should I have let the loop run longer, or will my loop eventually "wear in"
And before anyone ask's, the thermal paste was applied as i normally do, as i have done before without problems, all the thermal pads were applied onto the RAM etc, the Loop is running properly, there's still very small bubbles left in the loop and helps me identify that the pump is running, and there is a current flowing. If anyone, who has a good knowledge on custom loops, can tell me if i should wait for the system to work, or if i have done something wrong, it would be greatly appreciated. If needed, I took pictures during the entire assembly, ie. applying the new gpu water block, installing tubing, flushing rad out with distilled water etc...
As far as im aware I have done everything right, but there might be something im missing.

So i found the problem, i was too quick to jump to conclusions, i had a hard thought about my setup, any possibilities, and seeing as the GPU was still cooling when it wasnt under load but not keeping up under load, was telling me that maybe the contact between the water block and the Die of the gpu wasnt overly great. Took the card out of my case, keeping all the tubing attached but un-plugging power, i applied a screw driver too all the scews on the back plate. When i first scewed on the water block, i thought that all the (around 10) screws were tight tight, we in fact not tight enough, i got a few more turns without struggling on 5 screws, plugged everything back in, and now it Idle's on 30*C, and wont go higher than 55*C when...
Could you please give us a link to this photo album so that we can potentially point out if any mistakes were made? Those temps are definitely way too high, it should be somewhere around 50C at the hottest given multiple other results.
 


Only had 3 "good" photo's, quality isnt the greatest

Lesson here for anyone with issue's when water cooling gpu's, if the scew feels tight, try to see if you can get it tighter without f*$%ing the thread, otherwise you wont get 100% contact from the die of the gpu and the waterblock.
