Hi, I have just installed watercooling in my rig and I have a query. I have a combined pump/res and been carrying out a dry run to check for leaks. So far so good. Anyway, I have cycled the pump a couple of times and tilted the case to get rid of any air. However, how can I be sure the system is free from air? Please see some pics
What I do is get as much air out of the system in the first place as possible when filling. You can do this by moving the case around, wiggling the tubing a bit and you will see air bubbles appear in your reservoir. Once I'm satisfied that the loop is relatively "bubble" free, I just use the PC as normal. Over the course of the next couple of days, I find that the water level in the res drops a bit, so I just top it up until all air is eventually expelled. I've been doing this myself, the last couple of days.
Oh god not good. Turned computer on and temps are 70-80c IDLE. Shut it down immediately. Made sure I removed the sticky film from the CPU Block and only used a tad of TIM (rice sized blob). This is only a CPU loop so something is definitely wrong here.
Sounds like the mount of your CPU block is not quite right to me. Re-mount it making sure its on properly
Found the cause. The molex connector was not pushed all the way in. Must have come out slightly when I put the side panel on. Now idling at 34c
Also lay the case on its back, as this is the best way to remove air from the CPU block With mine with I first turn it on the level in the res drops as there some air that refuses to come out of the rad and the pump is compressing it. Noise is a good indicator if there air in the loop.
Quick question. I have a rs240 rad with fans placed between the rad and the tip of the case in a pull config. Would it be better to switch the fans round so they push air from the top of the case through the rad? Overclocking result for 4.01ghz showing 74c temps which seem high.
Whether you go for push or pull (pull is better with 25mm fans iirc) always feed your radiator fresh air, not stale case air.
I use mine as an exhaust, but then my case has much better airflow than that one. I'd have them above blowing air into the case as you get much higher pressure on the blow than the suck
Must of read your mind as that is exactly what I have just done. That way the rear fan can pull hot air through the back.
Update- Temps dropped down to 69c (did peak at 71c but been steady at 69c for some time) So is 69c any good on a i7-930 water cooled at 4.01ghz?
Setup is I7-930 XSP RS240 rad x2 gentle typhoon EK HF waterblock XSPC pump/res combo Temps at 78c for 4.2ghz. Want to keep it low 70s if poss. Got to say, a little disappointed with the result. Are these temps way off? If so, what could be the most likely cause?
Seems a bit hot to me. I'm running a i7 920 @ 4.3Ghz and was getting load temps of 66C Build log here
How are your fans setup? As this is my first venture into watercooling, I am not too sure how to sort this out.
Is there plenty of warm air coming off the rad? I'd pop a thermometer in the res to test the water temp personally, as that'll show the issue
Well, if the water temp is low, it'll be the waterblock area, if they're high it'll be the rad/pump So first test the temps, then we'll go from there
Brilliant thanks.vin your opinion what sort of temp should I be looking at for my setup? I know this varies greatly.
