Hi all

I have been reading up on watercooling recently because of how hot my 470 gets. Now I also thought that if I am going to go through the trouble of creating a loop for my gpu I might as well remove my H50 and add in my CPU to the loop. I will also be overclocking my cpu, hopefully will be able to get 4Ghz but will see how far I get before temps take over.

Initial plan for loop is
res -> pump -> 360 rad -> cpu -> 120 rad -> gpu -> res
OR
res -> pump -> 360 rad -> 120 rad -> cpu -> gpu -> res

My hope is that with an 120.4 of radiator I should be able to run the fans quite slowly and reduce noise.

A few questions I have which I hope you can answer

1. Is it better to run the same fans on the radiators or is it ok to run different fans? At the moment I have a 2 cooler master fans, 2 akasa vipers and an akasa ultra quiet. So I could use a mix of those fans on the radiators or pick up some yate loons or scythe GT's.

2. Is this spec alright for cooling my set up with reasonably low rpm fans? (fittings might change depending on final loop)

Edit: 3. If I leave the standard 230mm fans in the front and side, can anyone forsee a problem with air cooling my motherboard as I wasn't going to watercool it.

Thanks for the help.

No problem with running different fans on the same rad, unless you mount them in push-pull, in which case it would be a good idea. Fans on one side only don't have to be the same.

Spec looks fine to me.

If you currently are using a H50 on the cpu, and your case fans cool your chipset ok now as is, then there should be no difference after you go custom.
 
GT Stealth needs high speed fans to be effective, SR1 is a low speed fan rad that responds well up to around 1400rpm. Maybe look at a different 120 rad e.g. XT 120 or Thermochill PA120.1

Better to try and match fans where possible, but as said more important if running push/pull

Mb cooling sounds good with existing fans.

Didn't think there would be but thought I would check anyway. I am trying to work out my loop as best I can as to order everything in one go but I think I could get away with push pull on both radiators so may do.

Sorry that is my fault, in a rush a picked wrong radiator. I meant to pick the SR-1 120 mm radiator though I notice that overclockers don't stock them :( I will look into those 2 rads though to keep order together.


I have been searching for a while trying to work out the watts I have to coool from a gtx 470 and 1090T @ 3.8 / 4 Ghz to roughly work out Delta T and rough fan speeds but I can't find the info. Or is just these watts are the figures that the cpu and cpu draw? so I can just use one of the on line calculators.

Thank you so much for all the help.

Bit of a bump for this, calculated wattage from suggested link from skinnee and estimating overclock it came to 380 W. Now looking at the graphs, again from skinnee labs, I would have to run yate loons at around 1200 rpm to keep delta under 10C. Though this is based off watt calculator and only for a the 360 SR1. Is it possible to factor in having a 120 mm radiator also (given that I will for another low FPI again, maybe even 120mm SR 1)

If the wattage figure is the maximum then that should mean about the maximum I have to run my fans at is 1200rpm. So thinking maybe Yate Loons or maybe Silent Eagles 2000's as would give head room with the estimations.
 
Sounds about right but I think you should be fine with a 360 on its own personally, but you can never have enough rads :) well you can but if you can keep them in the case then you should be ok :)
 
I think for cooling my machine a 360 rad would be enough but I am hoping to be able run the fans as quiet as possible so more rads the better :D My limiting factor is I want to keep it all inside, though had my case open for troubleshooting tonight, I need to measure but I might have enough room for another 120 rad in my spare 5.25 drive bays. A bit overkill possible but every rpm slower I can run fans the better.

Thanks for all the help again guys.
 
Alhtough more rads is always best I'm cooling a i7 950 plus two gtx470's and me fans are on tick over. Unless going for really high overclocks, more rads aren;t really needed.
 
Hmmm the drive bay rad was/is only a very loose idea. What rad set up have you got then Greebo? Looking through your post history is it just the thermochill 120.3 rad? or have you got other rads?

Ended up with an xspc rx 360 rad, d5 laing pump with v2 top, 3 x san ace 38mm fans.

Temps of the gtx470's max out at 53C, cpu at 4.4Ghz maxes at 63C. I could improve the temps but why bother? Everything is happy. :D

Interesting, though that rad has got more fins (9 vs 15 FPI) Just from looking at the 360, if the calculator is correct then 1200 rpm fans are need for full load (though I know this is rarely going to be an issue) but I would rather keep my fans sub 1000rpm (or even better constant 800 rpm) which is why I am looking at extra raditors.
 
Don't blame you tbh. In fact I must admit I bought a 120.1 XFC rad to add to my loop since it was only £16.

All extra cooling helps ;)
