Just an fyi for the future
Thanks I didn't add one as I bought a res, do you think it's still worth getting?

i just pour distilled water into my reservoir and turn on my pc.
as pump is flowing water i keep pouring water. (never trying completely topping off on purpose)
pump is making noise and i leave reservoir cap off.
after 10 minutes flow makes gurgle sound and reservoir water level drops.
i add more water and open bleed screw on radiator.
wait til a steady stream flows out from bleed screw into a bucket.
eventually all bubbles in reservoir/radiator are gone and pump makes no noise.
tighten bleed screw, add ptnuke and cap reservoir.

beware***
while pc is off and water is in loop never have reservoir cap off and bleed screw open at same time. water will gush out the top of the reservoir.

Is it normal to have bubbles in the reservoir?

I have loads in there More bubbles in the res than in the tubing

How do I remove bubbles from the reservoir?

They'll start disappearing over time, it's normal.

Also, it's been noted that a small drop of dish washing soap helps break water tension. Bleeding takes a fraction of the time.

Bubbles can decrease cooling performance

Air doesn't conduct heat as well as water and the last thing a water cooler wants is air in his system

Infact the two things a watercooler doesn't want is trapped air and leaks

Thanks, I'm gonna run my loop with the res lid off.

Loads of bubbles have gathered in the res which is good, now they just need to get the hell out of my res

I take it taking the lid off the res, gives the air an opening to escape to?

Unless you fill your res right up to the top there will always be air in it. Bubbles are just pockets of air below the very surface of the water so really all you need to do is let them disappear on their own. You can help get all of the bubbles out from your components but there's not any way (that I know of at least) that you can force your bubbles to disappear instantly.

Yes you can take the lid off your res if you wish. But remember that air doesn't just go one way haha.

I personally fill my res up in stages. Maybe half full so there's enough water to circulate through the loop and then once the majority of bubbles have come to the surface, I top it up completely because otherwise I get foam buildup. (it's a long cylindrical tank that sits horizontally in the top of my case)

Well so you guys know, I left my pc running with the res lid open, and the majority of bubbles are gone.

I didn't need to tilt case, shake case or anything else.

Thanks for all the advice.

Hopefully others who have the same problem will find this thread useful.

I found running with the lid open was a bad idea. If a big bubble came up, sometimes the fluid overflowed or dust and general crud got into the loop.
