Why Quick Discconects are so Awesome

[NaeKuh]

Well, cuz of my friends, well i think there more enemies then friends.

I underwent a SLI bridge change.

I wanted to show you guys how easy it was because i had quick disconnects.

The problem with QD's is they are flow killers. But on your GPU loop, the 3-4C's wont help your overclocking at all.

So i am gonna show you why losing those couple of C's is WORTH it on your GPU loop.

My Loop started like this:


What i needed to do was pull the QD's off so i can get at the cards and drain the cards without card removal.



Tissue is the best leak detector. It bunches up and you know instantly when its wet. I put them on my QD's because you'll leak a few drops. Not a lot, but still a few drops.

Here is my QD's off and to the side:


Once QD's were pulled, i needed to use my drain line QD:


You guys know the rest... So i'll skip the elementry stuff.

Once water was evacuated from the cards, i pulled the SLI bridge:


Installed a Bitspower Dplug. To make it work, you need 2 koolance couplers.


After bridge was installed, i do my leak test live. I once again put tissue arround the new modified area, and do another 5 hour leak test while live.



So guys tell me now. Is the 3-4C really worth the convenice QD's bring? Total SLI bridge time replacement took no more then 10min.

Thank you for reading.

good info!

[sniperbob]

great little log of the whole process. It looks simple enough., and great idea using another QD for a drain line!

[Vapor]

I'd be surprised if it's even 3-4C....blowing through a coupled QD is pretty easy. But I suppose I'll have some actual numbers soon enough

[NaeKuh]

I was talking to gillbot and i asked, should i make one.

He was like might as well.

I put in the extra flash for snipe, and skinnee tho.

If the performance drop is 3 - 4c, I have to reconsider my plans
Is it really that much?

im picking high numbers.

in actuality it depends on your cooling supply.

For me it would be around that much cuz i have more heat on my gpu line then cpu line.
2 x HD4870X2 = massive heat station.

That isn't a SLI bridge fyi.

[NaeKuh]

That isn't a SLI bridge fyi.

its a dual card passover.

i know, its a habit of calling it a sli bridge.

A good thing to note is that we actually rate all our QDCs for total flow-through.

VL2 have a 6mm flow-through
VL3 have a 10mm flow-through
and a week or so ago we released VL4 with a 13mm flow-through

Picking the right shut-off valve can almost eliminate a noticeable performance drop.

[NaeKuh]

dean you guys need a variable bridge.

The ones you have are very selective.

:X

[Utnorris]

I use QD's from Koolance and it is SOOOOO easy to fill and drain that I don't mind swapping stuff out anymore. I use the VL3's and I don't think they hurt me at all.

Its definitely something we have considered, it will depend on demand and feedback from customers regarding current items.

[ILikeCosmosS]

you know koolance just created the vl4 model for there qdc
they are extreme flow i dont think they will kill your flow at all i saw them at performance-pcs

I have VL3s here, definitely don't seem too restrictive.

Question though, what are the inner springs made out of?

Oh, and any plans for a VL# line with female G1/4 ends? VL4s with the ability to switch barbs/fittings would be nice (like VL4s with 10mm compressions )

[zeroibis]

Thats why I have mine setup the same way!

[Tom128]

I never even knew these existed. The ability to have shutoffs on both sides of a piece in the loop would make working on just a part of the loops so much easier. Wish I had know about these!

I need to get some of the VL4 QD's then.

[Jokester_wild]

although that seems very handy for you. I don't really think draining a system is all that troublesome.

[zeroibis]

I think it depends on how often you need to disconnect it and what sort of setup you have.

Love this, this is the right evolution for W/C: usability and ease of use FTW Thanks for sharing NaeKuh

[T_Flight]

I've gotta get some of these when I move my stuff over to my case. I need one big one for a drain, and want to use them on other parts in case all hell would break loose and I'd need to pull the loop down.

I'm at that stage now where I've got it setup and running good, but don;t wanna take it apart becasue it's gonna be a pain to break loose. I'm gonna have to use some vise grips and paper towels in strategic locations.

At least I don't have a AA Battery for a T-Line Plug now.

[ILikeCosmosS]

skinnee i want to know if they restrict because the are posted on performance-pcs along with the new koolance compressiosns that work with 1/2 id 3/4 od

[systemviper]

me likey, i think i need to get a few.... thanks for the info!

+1 Only reason I would not get these at this time.
