So despite buying the Thermalright TRUE 120 and 6GB DDR3 OCZ RAM for my Core i7 920...I am still not satisfied with my temps...the CPU is now OC'd to 4.2GHz...but idle temps at this speed are at 45C and above and this is after lapping said CPU.

So now I want to try water cooling as I know this will give me the temps I want. If you guys can please recommend the best kits at around £150 or what best bits to buy (CPU block, pumps, radiators, etc) so I have a good understanding of what to get.

I may take a look in the Members Market if there is anything worth getting from there.

Thank you all in advance. :D

What are your full load temps like.

too high like hitting 90C...

reflux thanks for that...thats pretty much was I think looking into anyway...price seems about ok too...I will buy them bit by bit I think... :D

Ah yeah, get 7/16'' tubing (not the 1/2'' stuff I put above) and 1/2'' barbs. To get the tubing on you have to dip the ends in boiling water to soften them up. Because the sizes are mismatched, but only a little, you get a very tight fit.

Just get some standard worm drive clips; OCUK don't sell them but other specialist retailers do. They're much better than carpy plastic clips.

From my experience with watercooling, you HAVE to take your time setting the loop up and be very careful to check for leaks. If you use non-conductive coolant then you should be OK if it does leak, but it's not 100% reliable. I specced 3m of hose which is enough for my CPU loop with a bit spare incase I mess up the cuts.

Nice one thanks for that will bear that in mind :D
 
well if anyone has any pics of their watercooling set up to give me an idea of what is needed to get this up and running that would be much appreciated :D
 
right i have received some parts of my water cooling stuff.

I got 3m worth of 7/16" UV blue tubing of 3/8" ID and 1/2" OD. Along with these I bought TFC Compression fittings with G1/4 thread to be used with said tubing. However, when I put the tubing on the fitting, the part to screw them together doesnt fit onto the tubing. I am going to upload a few pics so you can see what I mean.
 
Right here we are:

This shows the tubing and part of the compression from the inside:

This shows the tubing connected to the other part of the compression:
12052009680.jpg


This shows the tubing with the outer compression. as you can see the outer part only stops are that part of the tubing:
12052009681.jpg


So where am I going wrong? Have I bought the wrong sizes? :(
 
so buy 1/2OD tubing rather than 7/16OD tubing? hmmm I thought using 7/16 tubing will have 1/2OD on it...man this is so confusing...but its all about trial and error right? lol...thanks mate...more tubing it is...:D

It's not trial and error - it's reading instructions and advice.

7/16 is 7/16
1/2 is 1/2

7/16 (which is smaller than 1/2 [8/16]) and will fit very snugly on 1/2 barbs.
BUT compression fitting are different - read the sticky and please do some research before you get water all over your pc.
It's not differcult or elitist but you need to be careful and know what you are doing.

Edit: Oh and compression fitting are a pita if you get your tubing even slightly wrong.
It's the reason people don't recoment them to first time users.

Thank you but just to clarify I have been researching and research over the last few months on water cooling...the whole barb, fittings, tubing side of things is what confuses me the most, hence why I have been closely talking to reflux about these and he has assured me of what I need, but as I said I got confused over the tube sizes to work with the compression fittings...I have never done water cooling before purely for the fact I could get things wrong...I may have bought the wrong size tubing but at least it means if things work out, i can use the tubing on one of my other machines and water cool that using 1/2" barbs...

In the meantime I will purchase 1/2" tubing to with the 1/2" compression fittings I have...if anyone has any objections please say so now otherwise I thank you all with your help and suggestions :D

To the OP, in case you don't grasp what is being said, if you look at the last of your pictures, the "lose part" is the fitting you have on the end of the that tube. That fitting should first be on the other way round, and second should be able to freely slide up and down the tube. Clearly the OD of the tube is much too big for that.

hence why I posted the pics for all to see what i was talking about...i realised this when i put the tubing to the fitting...now i know what exact size tubing I need...
 
Bubo said:
Hold, make sure you get 1/2" OD tubing, which is usually 3/8" ID tubing, if you are sure your comp fittings are design for 1/2" OD tube. I won't mention 10/8mm tube. Oops I just have. Most people when they refer to tubing will say 1/2" or 3/8" without specifying they usually mean the ID.

Got ya...1/2" OD...so ignore the last post then lol...the compressions are:

http://www.overclockers.co.uk/showproduct.php?prodid=WC-012-FO&groupid=701&catid=193&subcat=1049

and they state they are 3/8"ID and 1/2"...
 
Bubo said:
To be absolutely sure take a ruler to that lose fitting in the last picture and measure the diameter of the hole. If it is greater then 12.7mm then it will at least slide up and down the tube you specify above. I have to take your word for it the compression fittings you have are designed for 1/2" OD tube as I have no experience of them myself, and the common ones I have seen have been designed for 10mm OD 8mm ID tube.

Measured and its definitely smaller than 12.7mm so the tubing I bought with it was definitely the wrong size...I have found the right tubing on a competitor site (since OcUK seem to be going out of stock on jsut about everything watercooling) so I will buy them there...

my slow edit from before.
Looks like you have tube that is 7/16 ID 5/8 OD
but compression fitting that need 3/8 ID and 1/2 OD - you need to buy some 3/8 tube with 1/16 walls not available here. 3/8 ID + 1/16 wall + 1/16 wall = 1/2 OD
Clearflex 60 and the XSPC stuff is surposed to work but you will get kinks :( as the walls are 1/8 thick giveing 5/8 OD
Masterkleer Tygon and Feser all make the stuff.

ID inside diameter - OD outside diameter

Sorry for sounding harsh.

It's ok...all this watercooling lark is really confusing when one doesn't know what is needed...but at least with some guidance I will get there eventually...I dont expect it to run smoothly nor do I want to do it quickly...hence the lengthy buying process and making sure I get all the bits right...I expected hiccups along the way and I am sure there will be more to come...:D
 
Bubo said:
The hole is smaller than 12.7mm? So it must be designed for 10/8 tube? You're getting me confused now. To be absolutely sure, looking at the last picture in your set above, the fitting which is on the tube, the diamater of the hole facing us in the picture, is less then 12.7mm (1/2")? What exact diameter is that hole?
Click to expand...

lol...no...sorry it is 1/2" exactly...no bigger no smaller...
 
Man why is it never simple with water cooling stuff? lol...right here is what I have decided on:

1/2" OD tubing (thats 3/8"ID on the sites since they dont state the OD all the time)

and that is that :D
 
Bubo said:
Aha, so it *will* at least slide up and down 1/2" OD tube, which is what you want, although it will be snug.

Snug is good...snug can be very good...I like the idea of a snug fit...just wish I had a woman like that :D
