Need advice on watercooling

post #1 of 9
Thread Starter 
I have been looking at some water cooling systems and i needed to get some info on radiators. I am thinking about getting two or three radiators because i have a big box. But one of the main reasons i wanted to do that is because i want my cpu really cold. But the question i am asking is if you have more radiators will it drop you water temp alot or not. and if you have any suggestions on a water cooling that is good and will alow me to overclock to about 4.0ghz with a 3.0ghz pentium 4 with 800mhz fsb. Thank you.

If all you're cooling is your CPU, another radiator isn't going to do much given you're using a medium sized one in the first place (like a chevette heatercore). W/ a chevette heatercore and just your CPU being watercooled, your water temp is going to be maybe 1C over ambient temp after leaving the rad. Adding another radiator might get it down a half of a degree more.

EDIT: Also the loss of flow (GPM) that the second and third radiator will add to the system will cancel out better temps. Probably leaving you w/ worse performance.

Thanks for the info. I wasnt going to just watercool my cpu. I am going to watercool my chipset and video card and my harddrive. and i know what you are saying about loss of flow. I am also planning on getting 2 more pumps to increase the flow.

That's some important info to include . I think if you have the room, go ahead and run 2 rads and 2 pumps. Two should be plenty for that.
I don't think it's very good on the pumps to run 2 in series, so parrellel would probably be better. Probably should research that a little more though.

He could also run two seperate systems, if he had the room.

See what I mean? One pump/rad/res for your cpu and harddrive...then another pump/rad/res for your GPU and chipset...THAT WOULD BE AWESOME! Two different colored UV dyes...some UV lights...oh man, I may have to try that one of these days!

Let us know what you think, and what you end up doing.

I agree that would be awesome. But i am looking at a new case. I couldnt find a case big enough for it. If you find one please send me a link.

I like the idea of using dual circuits for cooling (although I am not experienced enough to tell you if it is a good idea or not.

I have two discrete circuits in a Xigmatek Elysium case, with a front-mounted double in a dedicated circuit with pump, rest and water block on a 6-core i7, which comfortably clocks up to 4.2GHz and is rock solid.

I then have a top-mounted triple radiator in a second circuit, with a second pump and reservoir, cooling my current single-card GPU, which is an nVidia GTX-980...

I had this setup with an earlier card, namely the slightly hotter GTX 680, and it was absolutely perfect. I have just purchased, but not yet fitted, an nVidia GTX 1080... I run a triple-monitor setup using W7/64 and Mint 18/64 and the system is rock solid and near silent. I have 5x Noctua cooling fans on the radiators, which are about 15db each and only really audible if you put your head down by the case. Lastly, I use a monster, 1250W PSU. I don't need anything like that amount of power, but when the PSU is running at below 40% load (which is about 500w) it does not need fan-assisted cooling, so is also completely silent... My last trick for low noise and good performance was to use only SSDs... I have a small, front-fitted 4-drive adapter that goes in a CD bay and let's me hot-mount up to 4 x 2.5" drives, at full 6Gbps SATA speeds...

So yes, absolutely look around for a decent case with plenty of room and you will be able to build a stunning system. And, the real advantage of goi g dual circuit is that you don't need to start with two... You can put in say one circuit for your CPU on day one, then add a second for a GPU when funds allow...

More pumps will only increase head, not flow rate.

with that much hardware being cooled it might be a good idea to really look into loop design, depending on how it is done with two pumps, they can provide a great high flow rate on a water loop.
http://www.overclock.net/t/1573189/serial-vs-parallel-9-6lpm

I have cooled my motherboard chipset, memory, two SSD's, CPU, and two GPU's all in one water loop, with one pump the total flow rate on the water loop was 6.6LPM, with two pumps on the same water loop the total flow rate was 8.7LPM, so it really is all about how the loop is designed.
