First loop - bleeding

[Mr. Happy]

Hi,

This is my first post but I've been reading up here for a few months now getting ready for my first loop (I've been building computers for about a decade but never water cooled before). So thanks for all the info you guys have here, learned everything from these forums.

I'm almost finished bleeding my loop, but I'm not sure how to finish it off. I've gotten it to 99% water but there are still alot of tiny airbubbles left. I've tried turning, rotating, banging, and whatnot, a friend of mine even used some weird chemistry stuff to suck air out of the loop from the filport (got about a hundred and fifty cc's)

(I'm using a t-line btw and stupidly made it only a half inch long).

So I've been reading and searching and I found some odd references to leaving it on all night, and something about bleeding screws on the themochill rads, but nothing really...instructional.

As I gather I should just leave it uncapped and turn the pump on for eight or so hours (besides the leak test)? And what about the bleeding screws, how can I utilize those and is there a particular orientation they need to be? (the only one I can access is sideways because of how I mounted the rads).

Also, what exactly should my loop sound like? The pump makes a whirring noise you'd expect to hear, nothing terrible, although it changes pitch slightly over time and theres a slight dribbling sound from time to time. The rad's on the otherhand...sounds like it's raining inside those.

sorry for being verbose

Setting your pump to slow and letting it run overnight will help you with both the leak test and getting most of the air out. You will never get 100% but you will get most of it that way. All the rest you mentioned is just about the way everyone else does it so good job :)

Put your ears right next to the radiator (barbs) and turn on the pump, if you hear the "water" sounds it mean there still air in the loop.

Thanks guys!

I'm not sure how to set the speed on my pump (Liang DDC), I'm guessing though, you need a fan controller, which until now I always thought a silly waste of money and so..I don't have one :/

Ya sure!

She's a little messy right now, bleeding atm.

The fuzion for your viewing pleasure!

What you see:

Loop
2x Thermochill PA120.1
1x Black Ice Micro 2
(I wanted to work with the fans I had, rather than cut even more giant holes!)

D-Tek FuZion
Danger Den T-Junction (I was going to use a cheapy hardware store platic t-fitting but I'm not physically strong enough to push the 7/16 tygon over 1/2 plastic barbs all the way and it leaked.)

Laing DDC pump with Petra's top (It's hidden and mounted on it's side in the 5.25in rack)

Electronics
(this stuffs a little old)
ASUS M2N32
Athlon 64 FX-62 Windsor

A vomit inducing Thermaltake Toughpower PSU gets the job done

Not installed:
2x 500GB Seagate Barracuda 7200.9's in RAID 0
8GB G.Skill (PC 6400) (5-5-5-15 timings)
BFG GeForce 7950Gx2
Dinky SoundBlaster lolz

Other:
5.25 bay ciggarette lighter, broken floppy drive, million-in-one card reader, DVD bruner w/ lightscribe

So I'm only cooling my cpu right now as I'm planning on upgrading whenever the 89xx series hits. Hopefully the 8950GX2's (if they're real) will have a nice and small PCB (ya right) so I can finnally go quad sli :devil: I don't really see the point in cooling your HD's, I know, I know, google was using refrigeration for that study but it still worries me. And the mobo has a nice heatpipe on the chipset that gets the job done good enough for me.

This isn't for just playing games, I also make games.


So back to my problem, the water is just flying around my loop right now. I assume I can build some sort of voltage regulator so slow down my pump, anyone got a schematic? Haven't broken out the soldering iron in way too long lol.

I had an idea last night, since bleed time is somewhat relative to surface area on the fill zone (making res's bleed faster), and because with a t-line the water is going in the same place the air is trying to come out, I wonder if adding a second, extremely short t-line at the top of the case (for air to escape), and a long t at the bottom of the case (for filling) would help. Partial pressures and all that stuff...not that I'm about to do it but it's an idea?

Nothing wrong with Tt toughpower PSUs. Their others aren't so great but the toughpowers are good units.

Thanks CaptKrunch!
I didn't want to mess with the bleed screw because I wasn't sure what would happen but you eased my mind. I unmounted my T-Line from the top of the case and raised it about six inches, then released the screw, and the level in the tubing dropped a good three inches! So I filled from the T-Line, sealed it up, ran the pump for a few seconds, and did it twice more and now I don't hear so much as a hint of any trickling even when I put my ear up against the various components. So thanks!

True, I'm just generally against Thermaltake on principal, not sure why hehe. The PSU was free tho :)

free? I envy you :p:
