Guys,

I have a question (as I am a complete noob when it comes to water cooling)

I got a kit which i was due to connect to the fusion block on the striker I extreme but since swapped it for the rampage as the striker II is unstable.

So I currently got compression G1/4 connectors and tubing 8x10 is it worth me upgrading this to 1/2" tube as I wil only be coling the cpu with my triple fan radiator?

Also how would i do it can you get different size connectors to change from the G1/4 connectors i have now? Is there such thing as a connector with the same G1/4 thread but increasing the tube size ? or is this going to be limited by the pump as it is originally for a 8x10 tube.

And in terms of cpu water blocks for 775 socket is there a good one that has the bracket attached to the block so that you simply drop the block over the socket and tighten bolts rather than the stupip AlphaCool NexXxoS which i have hassle installing and lining up the block with the central screw etc making a mess with the thermal paste.

Your help guys is appreciated and if you could give me links to the parts needed and explanation on how to do it would also be welcome ;)
 
Upgrading to ½" - probably not
G1/4 is the thread size so it should be quite easy to find G1/4 thread connectors with the Outside Diameter" of the tubing you want to use
Yes
Mixing tube sizes isn't great
never heard of a good block that doesn't require through motherboard mounting
 
the g1/4 thread is just the type of thread the barb uses - 10/8 fittings and 1/2" fittings are interchangeable. It's not going to make any difference to your temps (less than 1 degree), so unless you really want to change for looks etc I wouldn't bother.

So are you using the nexxxos or the fusion atm?
 
I thought bigger tubing made more of a difference than that? Hence the recommendation to use 1/2" or 7/16"?
 
Yeah, you'd think so, but apparently not - although 1/2" tubing is just under 6 times less restrictive per unit length than 10/8mm tubing (Poiseuille's law - restriction is proportional to 1/tube radius^4, and directly proportional to the length of tubing used), the restriction of the blocks, radiators, fittings etc is so much greater that the impact of tubing is minimal for the lengths of tubing used in watercooling loops.

AFAIK tubing size used to make much more of a differnce when flow rate was everything because old blocks had very little restriction. I think there's a comparison by carthar on the net somewhere and it showed the differenace as being neglidgable with modern kit if remember correctly.
 
it all depends what country you're from.. ze germans and a lot of johnny foreigners like the thin tubing.

In great britain we like fat, stout, stodgy tubing hence why people recommend 1/2" or 7/16.

There's no measurable difference I've ever seen in performance though although I gather the thinner stuff often bends easier? Anyway, masterkleer would do that for you.

In terms of mounting, no I've never seen a decent block that doesn't require through mobo mounts but things like Dtek fuzion/swiftech apogee gtx you fit the moutning mechanism first then the block so it's entirely possible to take the block off with the motherboard installed, change cpu/paste whatever and then refit the block withuot having to take it all out.
 
Oh yeah, g1/2 is standard for everything except thermochill rads that use something bigger, I forget the measurement and the blocks I mentioned use a thumbscrew at each corner so they're a fair bit easier than nexxxos blocks to fit iirc.
 
yes thats what i meant fit the threads through the motherboard holes and then install board and then you can simply sit the block on the chip and tighten the 4 corner bolts. As the one i have now is a pain as you have to hold the block whilst fixing the bracket to then line up the centre of the block with a centre screw to keep it in place.

Right pain in the A***

I already have the 8x10 tubing so I may as well use that really ???
 
no performance benefit to changing but it will look much nicer.. I guess you have to decide if looks bother you and if so whether the outlay on new tubing and barbs is worth it for you.

If you try the difference between 3/8" and 1/2" tubing on his estimator and select your setup you will see how much of a difference it makes

I tried a laing ddc-3.2, thermochill 120.3 and d-tek fuzion v2 with quad nozzle and the difference was 2.04gpm to 1.88gpm so about 8% in flowrate which is not insignificant.

However, how this would compare with actual cpu temps is a different matter but based on the better the flowrate=the better the performance it will make a difference and if doing custom and for what tube costs, every little helps.

On my custom setup (not the best but cost £97 :)) as follows:

Laing d5 pump
D-tek fusion gfx
Swiftech 220 rad
Danger Den cpu block with nozzle 1

The difference in tubing is only 0.06gpm so only 4% but that's enough to get me from the good section into the great section as far as flow rates go.
