Quick Disconnects - Good or Bad?

GoogalyMoogaly · 29 Aug 2011 at 17:34

Hi,

I suspect this has been asked before (possibly even by me) but a quick search didn't bring anything up.

I'm thinking of adding some quick disconnects into my loop when I redo it. Just wondering if this is a good idea? I'd probably look to put 2 or 3 in there (separate the pump & res, the radiators and the cpu/gpu blocks).

So do they cause a big problem with flow rates/restriction or are they ok in small numbers?

My loop will hopefully be:
MCP35X + XSPC dual bay res
HeatKiller 3.0 CU CPU block
XSPC Razor 480 GPU Full Cover block
EK Coolstream XT 120 Radiator
Black Ice SR-1 360 Radiator

I believe both the CPU and GPU block are more restrictive than some on the market so would adding 2 or 3 Quick Disconnects into the loop ruin the flow to the point where it's an issue?

Thanks.

Never used them myself either so can't really help sry.

Lol

they are good if your swapping parts all the time other than that there.s not much point

they will lower flow rate but its not going to be notable unless you put loads in

There have been some reports of problems with Koolance QDCs.

I have looked into these a number of times, they are generally quite restrictive which always puts me off doing any further research.. So I just end up fitting a suitable drain point to my loop making maintenance easy without filling flow.

I have two sets of the Koolance VL4 - extreme flow - and are as restrictive as a 45 bend.
Flow rate is very important to me so the VL4 are the only ones I'd use.
Great bits of kit - but only worth it with external rads or lots of upgrades.

Have used the Zalman ones on the past (part of the Reserator2 I own)
These are way more restrictive.

There are also plastic ones from CDC with 1/2 barbs - these are massive but excelent

Looks as if the new batch of 'non drip' QC are not so good after lots of uses.

One of the only uses I could see for QDCs is for external parts. Unless you change your hardaware ALL the time that is.
