Does this looks like it'd work? Just to cool my CPU.

I have a 902
I plan to mount it all within my drive bays, I only use 1 HDD and 1 optical drive (I may add a second HDD) so that leaves 6 bays available to use :)
Wanting to go - Fan|Rad|Fan <---- air


Will this work?
What fittings do I need?
Can you suggest improvements? (have to look good ;) My theme is black and aquamarine blue :) )
What sort of temp improvements can I see over my Fenrir?
I'm willing to go second hand (once I get MM access >.<) and my absolute max budget is £150.

Thanks in advance :)
 
Yeah, that'll work. It'll be limited by the radiator surface area, so fitting a double radiator would be loads better. A single 120mm radiator has roughly the same surface area as a big air cooler so performs about the same, a double 120mm radiator is loads better. You've forgotten barbs btw.

I think second hand is a good idea. A 240mm feser went for £35 a week ago iirc and is easily worth the fiver over the radiator you've picked. The waterblock is excellent and cheap enough that buying new is reasonable. Ideally you want a second hand laing pump if one comes up, either 10W ddc or a D5. Failing that the pump you've linked to is still much better than the xspc reservoir pumps.

So, in summary, get a double radiator and try to get a better pump. There are other minor details, like putting a drain line somewhere (it's surprisingly hard to get water out of the loop without one), and whether you can fit shrouds between the fans and the radiator. I'm assuming you'll want to add other things into the loop later on, but If you don't then getting a better pump doesn't matter much.

Looking good for an initial spec, and it's nice to see you've done some reading before posting.
 
Thanks mate. Space is the biggest issue in the 902 so I'm trying to be creative lol.

My system as current (I am an surgeon in paint ;) )

So....
Mount a double rad behind the fans.
A single bay res above the HDD (Should I put it above the rad instead?)
As for the pump....
The unlabled hole I've drawn is where my cable grommet is. I was thinking I could move it closer to the PSU like 2 inches and route the cables through it as tightly left as I can. That should give enough space to put the pump behind where the HDD is now.

It looks workable to me but It'll be my first WC attempt so if I've missed something please point it out so I don't end up weeping in front of my frazzled hardware :)

I don't trust bay reservoirs, they look too likely a source of leaks to me. This is perhaps unfair as I know of few references to them actually leaking. I'd prefer the xspc res top if using the ddc, or the swiftech micro res otherwise.

Check there's space around the fans, as a radiator sticks out a bit (i.e. it's longer than 240mm).

It doesn't really matter where you put components once you've found somewhere for the radiator, as waterblocks are smaller than heatsinks, the pumps are fairly small these days, and reservoirs are optional anyway.
 
A 250ml or so reservoir just makes it easier to fill the loop, you fill the reservoir, run the pump til the res is nearly empty, then refill it. With a T line you have to spend ages adding a little bit of water, running the pump, repeating. Time to equilibrium won't be significantly changed.

T lines, as an alternative to a res, offer fractionally higher performance for significantly more effort.

I'm hoping to have a 150 liter reservoir after moving house, in which case I should be able to turn all the fans off for ages. Can't wait :)
 
I'm just looking at running 2 single rads. 1 at the rear fan and 1 at the intake fans. That would give me the surface area of a double rad but save 3 drive bays for a fan controller (and hdds etc)

Asides from the extra tubing/fittings there's nothing wrong with running 2 small rads over 1 bigger 1, right?
 
No real problems except maybe extra head preasure from 2 rads and the tubing.
But to be honest if you are only cooling the CPU it wont make any difference mate.
 
Ok hmmm...I thought the h50 "failed" because it's rad couldn't dissipate enough heat.
I do want my CPU at a stable 4ghz so I'll have another read and post back with a new idea.

Thanks again for the help people.
 
In short, that is the limitation of the H50. A thick 120mm radiator will perform better than the one attached to the H50, but not as well as two thick 120mm radiators.

Two 120mm ones perform very similarly to one 240mm one, the most I can fit in my case is a 240 and two 120s so that's what I'm using.

If mounting one over the rear exhaust, take care that it doesn't block airflow over mosfet heatsinks. I can fit a 120mm inside the case over a rear 120mm exhaust, but it starves the heatsink below it and only just clears the cpu waterblock. Unless you intend to mount it outside the case of course.
