Primochill CTR Phase ii blowout

[Whiskers]

Just been gaming on my newly watercooled pc and noticed that after quitting the temps weren't coming down, looked in the window to find the level in my res had dropped then notice the puddle on my top GPU and leaking out the bottom of the case. Powered off and looked inside to find the pressure had caused the bottom of the res to push off and leak coolant.

How could the fluid in my rig get this hot, when it got onto my hands it was nearly scalding, do I need more airflow, faster pump?

Any help would be appreciated

Cheers guys

My guess is that your pump has failed, meaning the fluid just sat there in the blocks getting hotter and hotter until the pressure burst your loop. Have you got your pump tacho wire plugged into your motherboard, and a warning set to sound if the rpm drops to zero?

The pump is fine, I do have the tacho wire hooked up and the system set to shut down if the RPM drops but it was sat there at its usual 2500 RPM the whole time

That's weird then, did you get any problems during the leak test part of your build?

No problems at all during the leak test, the system has been running nearly 24/7 since the water cooling was fitted in september but mainly at idle, browsing, this was the first time it had seen any high load for a long amount of time.

I think the hose that was coming out of the bottom of the res down to the pump was a little short so was pulling on the bottom cap of the res, this coupled with the pressure caused it to pop off. I've now managed to get the cap on tighter and put a longer hose in so it's pushing up on the res a bit, hopefully will help keep the cap in place.

The thing that's bothering me now is how it would appear I heat saturated a loop with 240mm x 30mm and 360mm x 60mm?! There are Corsiar SP quiet editions on the 240mm and GT AP14's on the 360mm, all at 7v. Maybe there wasn't enough airflow in what is quite a restrictive case, NZXT H440?

That is kinda worrying. What temps were you getting on your CPU and GPU?

Started off with the CPU hitting about 80 and the GPUs at about 50 when the loop was working but when it got saturated everything was at about 70-75

Right. To me, that sounds a bit on the warm side but others may well be able to comment. You will get a small pressure increase when temperatures increase, that coupled with the materials in the reservoir getting slightly more flexible when warm and the pressure the short hose applied to the cap caused the leak.

So fixing the hose will allow the reservoir to stay shut, and leaving an air gap in the top allows room for expansion. That just leaves the temperature issue - if it is an issue - which can be resolved by either running the fans faster or rearranging the radiator for better air flow. I'll leave others to comment on that side of things.

Temps way to high and will cause the tubing to leach plasticizer into your system causing a blockage and a blow out. The res is rubbish and your not the first to see them blow out, pop out ect ect.

You will need to clean your whole system , replace tubing and replace that res for a more reputable manufacturer such as XSPC or EK, Koolance, Swiftech ect ect.
