air bubble in cpu block

buzzlightweight · 24 Nov 2011 at 23:51

i have a big air bubble in my cpu block, i have an EK Supreme HF CPU Waterblock - Nickel Plexi so i can see the bubble.

i have tried -

shaking the tower
standing it on it end/side
squeezing the pipes
turning the pump controller to high and low

i cant think how to get rid of it and i think its effecting my temps, 4.8ghz @ 1.37v after 4hours prime peak temp 71c!

any ideas would be greatly recieved

I would suggest taking the cap of your res and leaving the machine to run on its own,
for a good few hours or maybe even overnight if its not going to disturb anyone.

This should push any water bubbles out of the loop that you have in it.

well its in my room and would keep me up so i will do that tomorrow ty for the advice

No problem, let me know how you get on with it.

Just make sure that you leave the system on for a good few hours to give it
chance to actually move the air bubble(s)

you sir are a genius! i crapped my self coz i heard a big "plop/splosh" thinking the worst had happened only find it had cleared!!!! it only took and hour, i will keep it open all day to see if it will clear anymore.

tyvm for your help

No problem m8 I'm glad to help you out.

Should notice a difference in the cooling now with no bubbles trapped in the system.

i diddnt know removing the cap off of the res gets rid of air bubbles?

edit: bad idea to do it mate

Seriously, I have corrected about 5 people about this myth in the past week. You do NOT need to unscrew the reservoir fillport in order to bleed a loop. Once you fill a water cooling loop, it becomes a closed system where pressure is equal. The total volume of the contents of your loop are not going to change, and the temperature differences your loop experiences will not be enough to cause any significant pressure difference.

The air that is circulating your loop will simply collect in the reservoir, replacing the water that was in it. The water then moves into your loop to fill in the space where the air was. Thus the total pressure of the system is the same as the surrounding atmosphere, meaning that taking the reservoir cap off does nothing.

There are many risks involved with trying to leaktest while having your res cap off, most notably spills. One of the best ways to bleed to shake and tilt your computer, and doing so with an open reservoir is incredibly stupid (Unless you want a mess to clean up!). Dust from the air can also land in your reservoir and dissolve into the water, effectively turning that precious distilled water right back into tap water.

I just don't see the point.

well i have not removed the cap fully just a 1/4 inch blank that is right on top.

im not worried and shadz advice was solid so im happy to do it and others (with care) should be as well.

shadz advice dropped 4c off my temps!!! respect to him

Thanks for that m8, and glad it helped with your temps, there will of been
air bubbles in the loop that you would not have been able to see so they all
will of collected when you took the cap off and then popped when they got
to the res.
