Enough cooling

Postby tom » Tue Feb 26, 2013 2:24 pm

I'm planning to liquid cool my system in the future. But I'm not sure if the radiators will be enough for what I want.

Here's my system:
Case: antec 1100
Motherboard: Asus 990FX
CPU: AMD FX-6100 (Overclocked to 3.8 GHz and would like to go higher)
PSU: Seasonic 1050
GPU: AMD Diamond 7870 (plan on crossfire in future)

Planned loop
Water blocks CPU-370SA
Pump: pmp-400
Reservoir: attached to pump with 80mm
Tubing and Fittings: ID 3/8 OD 1/2
Rads: Phobya 200mm top and 120mm back
Fans: Stock antec fan for 200mm and 120mm fans in push pull.

Need more details about if your cooling the CPU or the CPU and GPU etc to be able to provide more appropriate feedback.

My bad I was hoping to be able to cool both the GPU and CPU. Some day I may go crossfire and add a second GPU to the loop. Also is there a waterblock compatible with the 7870 because when looking it's not listed in the water block selection tool.

If you plan on only useing a 120mm rad then it wont do it , a 440mm 3x thick will if you dont OC . A 660mm will do it and have spare cooling . You should get better fans the Antec case fans dont last all that long but there easy to replace , I found that corsair make some realy good ones and the Koolance ones are very longlasting as well.
this is only my experance and very basic outline ,
basic ya know, the longer your coolent stays in your rad the better it gets cooled .

Sorry for not being clear in my first post. But I'll also be adding the Phobya xtreme 200mm rad on top along with the 120mm on back. I Could easily replace the fans for the radiators if need. Also I have added Gelid 120mm for all the places that didn't come with fans. Finally do you have any experience with bitfenix spectre pro 200mm on a radiator or anoter 200mm fan that is 25mm or thinner?

A single 120 can often be enough for a single CPU think of things like H80's etc however under heavy overclocking they don't always have the head room necessary to carry on with temperatures still remaining within most peoples comfort zones.

About the 200mm rad, it is great there are rads available for the Antec cases in those sizes however because of the fan options they don't perform overly well. Most 200mm fans may have high CFM rating but you also have to look at the size of them, they also usually have low static pressure which hampers their performance on a radiator.

With only one or the other caution would have to be taken with heavy CPU overclocks, with both you would probably be able to go to your hearts content. However adding a GPU to that with an OC'ed CPU you probably won't keep comfortable temperatures and will find yourself wanting more. I know depending on the size of the motherboard I have seen people sneak in 240mm rads with what your proposing to do where the HDD cage is.

I played with a CPU-360 and CPU-380 side by side and bench marked my results... the gap between the 370 and the 380 might be smaller but the 380 is definitely worth the price difference.

After looking into it further I see what your saying, so for starters I will just cool the CPU. If I were to add a 240mm rad along with the 200mm and 120mm would that be sufficient for 2X 7870 and the cpu with decent overclocks. Otherwise I can just stick with just the cpu, since I have no troubles cooling the gpu thanks to the case fans on the side. I'm also planning on doing a push pull on the 200mm and possibly switch to 180mm fans for higher static pressure.

What kind of increase would I receive going from 370 to 380 block because it's $20 increase and I have tough time justifying the cost. Also I like the look of the 370 better as the chrome doesn't fit with my case theme.

Finally would the 401x2 work well with my planned setup or would my original plan of using the pump base and 80mm reservoir be better?

Thanks for your help everyone.

Summary from the first round of test when I was testing 360vs380. Results are using MX4, I was also testing MX4 vs AS5 but not posting that along with this.

Temperatures below = delta above ambient (or at least what I used to record ambient)
They are also core temp readings from the CPU not surface temp readings.

CPU-360
@100% Fan Speed
Idle: 2.8'c
Load: 14.3'c
@40% Fan Speed
Idle: 4.8'c
Load: 17.5'c

CPU-380
100% Fan Speed
Idle: 2.1'c
Load: 9.7'c
40% Fan Speed
Idle: 4.3'c
Load: 12.8'c

A performance difference like that makes the 380 an easy choice but like mentioned I'm not sure where the 370 falls in comparison.

Edit: also note that is is with the loop in my signature.

i might need to get the 9x120 rad if your getting those temps lol.
