Hi all :) I have been inspired by the Corsair H70 in my new build to try some 'proper' water cooling, so far I'm looking at these components -

OcUK Extreme H2O GeForce GTX 460 1024MB GDDR5 PCI-Express Graphics Card

XSPC Dual 750 Bay Reservoir & Pump - Clear

Thermochill PA120.1 120mm Radiator

I would also like to include the water block on my Gigabyte GA-X58A-UD7 in the loop but I can't make head nor tail of the fittings required to connect everything up.

I found the stock fans on my H70 to be quite noisey and have replaced them with Akasa AK-FN058 Apache fans, would a couple be suitable for this setup ?


I would like to order the kit for delivery on Saturday so if anyone could advise me I would be most grateful :-)
 
I'm not really an expert on the subject, so take my opinion loosely, but wouldnt a 120mm rad be a little under par for cooling a gpu and a cpu? Especially if you add the mobo into the loop also.
 
A 120 rad is not going to be enough for a mobo block and a 460. Mobo blocks are pointless on most boards as all they do is dump heat inot the loop and don't really allow any higher overclocking so you'll be doing for aesthetics. A general rule is 1x120 per block so at least a 240 rad.

For your fittings are you after compressions or barbs? Thermochill rads are g3/8 threaded so you'll need a cuple of g3/8 to g/14 adapters or some g3/8 barbs/compressions

What size tubing do you want to use?
 
Cheers JeffyB. I don't think the stock block on the motherboard is a full motherboard block ( tounge twister! ). The motherboard came with a heatpipe cooler which I am currently using, I could stick with that.

So a 120 rad would be enough for the gfx card ? If it isn't I'll need a bigger case, external mounting would be awkward.

I have no idea which would be the best size tube to use :-]
 
Just realised that mobo has one of those blocks on it, never use them. They are poorly made and are often aluminium, whitch will lead to galvonic corrosion with all you nice copper waterblocks/rads. Never mix metals in a loop. A 120 should be enough for a 460.

Tubing wise if using barbs i'd use 7/16id tube over 1/2 barbs with some clips/clamps. If you want compressions i'd go for 3/8id 5/8od tubing with compressions to match. I went slightly smaller as it's easier to route and you'll come into less issues than you would with large compressions.
 
They add a lot of restriction to the loop, won't allow you to overclock any higher on most mobos and the cost of the added blocks fittings tubing etc.
 
Motherboard blocks are great if airflow over the board sucks because you took all the fans away. Otherwise theyre probably not worth it.

The ud7 block is copper. Can you unscrew the barbs from it?
 
I'd sooner use 1 or 2 low rpm fans to keep some air flowing over the mobo than use a mobo block as i have in my build. Theres a lot less warm air in a watercooled case anyway, no heat spillage form the cpu or gpu so a lot less cooling is needed for the mobo.
