Couple of Watercooling questions.

post #1 of 6
Thread Starter 
Ok so I received a water cooling kit recently from my cousin and everything he included wasbasically this kit
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_202_972&products_id=33548&zenid=f70dd6f26469ba3a27b2f09276c4ebe3 minus the CPU Block. Instead he included the XSPC Raystorm block and also a 120 Extreme Rad. Right now I have the 120 Extreme rad hooked up for I didn't put any time into trying to get the 360 rad to fit my haf 912 case mainly because he said the 120 Extreme Rad would cool my pc + a gpu when I get a WC gpu. I would like some opinions from you guys if I should start trying to figure out where to fit my 360 rad? Right now my temps are nice but want the best out of this kit. I will have to fix up the 360 rad though how ever because it had/has some bent fins and also I need to paint it as well.

Currently I have installed
i5-2550k overclocked to 4.5Ghz @ 1.264Vcore
Temps are nice as I said above. Max temp at load is 55C-60C.
I have also overclocked to 5Ghz and ran LinX and my max temp at max load was 81C
I plan to have an EVGA GTX480 soon with a koolance universal water block in the near future if my friend ever gets his RMA finally sent to him.

The 120 Rad I am using right now is
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_457_667_671&products_id=25387.

I have been told by others the 360 rad would possible cool my CPU better and I would better benefit from the 360 once I include a GPU to my loop.


Some details on the fans I am using and liquid. Right now I have 2x120MM Xigmatek fans with a max RPM of 1500. They normally run at 1400RPM. I am using a mixture of distilled water and PrimoChill Ice, http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_381_303&products_id=23233 . I plan to some time in the future when I can afford it to buy another bottle of this PrimoChill Ice and use just it since I heat liquid additives cool better then just distilled water. I had to use a mixture because he included the PrimoChill with the loop ALREADY in the loop connected. During the shipping the PrimoChill Ice leaked leaving me with no choice but to mix distilled water in the loop so I could use and test the loop. I currently have the fans set in a push pull config obviously but as an exhaust on my rear 120mm port on my haf 912. I am going to try the push pull config as an intake to see if I can maybe better my temps some since my pc runs right below my AC vent.

Anyway just wanted to get some advice on which rad I should use. I do plan to upgrade my loop in the future, again when I can afford it.. Any and all input is appreciated. Thanks

These are my opinions in no particular order:

1. If you plan on adding your GPU to the loop then I would vote for using the RS360 instead of (or in addition to) the RX120. Those 480s, if I remember correctly, can generate quite a bit of heat. For just the CPU, though, you might not see much improvement. I went from a RS240 to a RX360 and saw no gains for a CPU only loop. Once you start adding more heat sources, though, the 360 should help quite a bit.

2. I personally prefer using straight distilled water with some PT_Nuke. I'm not aware of any data that shows that those coolants (like Primochill Ice) actual cool better.

3. If you are going to paint your radiator I would be careful not to paint the fins. I would suspect that you could impact the cooling ability if you paint them incorrectly.

Just my 2 cents. thumb.gif

That single 120 isn't going to be enough to do a CPU+GPU loop with respectable temps, IMO, but the 360 on it's own would handle the 480 and CPU just fine. Seconding distilled water and pt nuke, it's significantly cheaper than any of the coolants and cools as well or better than anything on the market. When it comes to painting the rad, you can paint the fins if you like, but make sure to do a very thin coat as a thick coat can reduce their performance. Personally, the fins aren't really visible through the fans anyway, so I'd just tape off the inside and respray the housing. A couple of bent fins won't cripple the performance (car radiators and air conditioners deal with this all the time), so if you're worried you might damage something while trying to straighten the fins, you may be better off just leaving them, as long as they don't leak.

As for upgrading: You may want to consider upgrading your pump when you add a GPU block and radiator to the loop. The X20 750 isn't a bad pump, but it does have a reputation for failing prematurely, and upgrading to a DDC or D5 pump can save you some reliability concerns.

Thanks. Yeah once I get up some funds I will be upgrading my entire water cooling. I got this because it was free. Also how can fins leak? Are you saying water runs through the fins?

Water runs through small metal tubes that the fins are attached to, the fins themselves won't leak but they are attached solidly to that tubing, and if you puncture that tubing you're in for a leak. It's not really difficult to straighten fins, I don't mean to scare you away from it, I just wanted to throw that warning out.
