Quick Disconnects

1143 18
Any body use disconnects anywhere in their loop?

I have an external quad rad mounted on my side panel. It's not a huge problem to not have regular access to that side, but it would save some minor headaches to be able to quick-disconnect the rad for easy panel removal.

Do these things really work?
Are they massively restrictive?

I'm looking for info on the fittings, not the company that makes them. Though feel free to flame the company to your heart's content if you know an alternative manufacturer of such a product that supplies Stateside.

Say Ira, have you ever looked at lengthening those little "nubs" that hold the valve open? ..to get higher flow rates.

No I've never used them much, I bought a set for 1/2" tube once, for a side loop, and ended up only using it for a couple of weeks.

Have you tried it?

Hey ira-k
You said the Koolance QD's were gonna' be highly restrictive. Is this because of the pressure threaded type connection?
The reason I ask is I've got a set of 3/8" inch Koolance threaded bulkhead fittings on my 2x 24/7 Q6600 DCing boxen, but they are the barbed type.

On one machine the low TDP eVGA 8800GS has a MCW60-R WB and the temps are about 1c to 2c degrees higher than the other Q6600 boxen with a eVGA 9600GSO (96) with a third party AC'er (water temp, air temp the GPU temp is about 11c to 15c degrees higher). These temps are taken from external containers sitting on my window sill and depending on how cold it is outside the temps have been very low ie ATM my GPU, according to Precision, is 22c degrees and my CPU, according to a calibrated RealTem program, is 12, 15, 15, 12, According to an indoor/outdoor thermometer in the outside leading duct it's 8c (43F) and according to another indoor/outdoor thermometer my ambient temp is about 18c (68F)


These temps were taken with the boxen using the [email protected] GPU2 client on core #3. I usually have the WCG clients locked to the rest of the cores. about 3c to 4c rise in CPU temps with the WCG clients

If I can find mine I might have to play with them, its been a while since I've seen them though.

Are those actually a 5/8" ID straight shot all the way through it? I just don't believe any of there claims, its probably more like a 1/4" ID.

I'm a flow freak to, if I was going to use any I'd use those nice Coulder in 5/8 or 3/4" with 1/2" tube, that should minimize flow loss.

Really if you can get by without them you would be better off. Keep fittings and tubing length to a minimum, thats just a general rule, if you have a real reason for extra tubing length or fittings its not going to hurt you that much, as long as you keep it in reason.

Oh Yeah, Its really noticeable isn't it, I could even tell a difference using those Colder hi flow with 1/2" barbs and I bet they are a lot less restrictive then those things.

the koolance quick disconnects add a bit of restriction too. they took off about 1L/min or .26gal/min from my previous reading. of 5.7L/min or 1.51gal/min.

hehe.. it was in my techstation thread.

Ouch. Is that for 2 full sets, male/female x 2?

EDIT: I think Martin tried some of the 5/8" or 3/4" Colder with 7/16" tube and they weren't very restrictive at all. I'll see if I can find it.

I might be thinking about copper fittings to, its been a couple of years.

Man what were you building..
..Thats the best way to do it, now you know for yourself.


I've always been tempted to use them, there just cool you know, and convenient to, but I cant get over the restriction any of them will have, I used them for a couple of weeks and couldn't take it anymore. A good drain--line is all you need and that just takes 1 T to make.

haha.. i was doing it for my test bench but then i got sick of the restriction and just scrapped that whole idea.

There just so neat though. If I ever find them again I should do a NB loop with them and a D-5 vario, I'll still have plenty of flow that way..
..


Hey I have a modded Corsair Nautilus with a BI rad in it, that thing has the Colder on it to, I forgot about that. I've got a DD NB block, I think I'll set that up.

billbartuska has me wanting to play with them now and try to bump up flow a little with them, I need to dig that thing out.
