5.25" Reservoir with pump suggestions? - Page 2

Here are some tests on that pump. Keep in mind that you are targeting around 1GPM for your flow rate as that seems to be the ideal. If you have 2 restrictive blocks in your loop, you will need a better pump. If you can find a low restriction block for the CPU and GPU than that pump should work with that radiator.

Flow does matter to some extent. If you can't get near 1GPM you will not get ideal results.

There is a lot of good information here on flow rates, pump/block/rad performance.

I'm assuming the $75 budget is for the pump and reservoir based on your posts...if I'm incorrect on that just let me know.

The XSPC pump you linked above is pretty good and hard to beat for the price. It doesn't get much love here on the forums because it's considered a budget setup and they're known to be a bit loud. I ran one in a secondary rig for a year without any problems and it was pushing through a 240MM radiator, 120MM radiator, EK Supreme CPU Block, and EK HD 6950 block. It didn't fail on me and besides the noise it did very good for the price. The person who bought it is still using it and to my knowledge hasn't had any trouble from it either.

Another good option for a CPU only loop is the EK-DCP 2.2 pump and the res that goes along with it. It'll set you back around $80 for the combo and will do just fine for a CPU loop. You could also pickup a MCP-350 / 355 pump and Swiftech micro-res for around $80.

Most people will recommend that you get a bigger pump because water cooling is a sickness that never lets go and will have you upgrading in no time at all...so it's easier to buy a powerful pump first and not have to worry about upgrading later.

Well, just as a reference, I went with a kit with that D5 bay res, actually the kit is here: XSPC Raystorm EX360 Universal CPU Water Cooling Kit w/ D5 Variant Pump Included and Free Kill Coil!

And I put it in to this PC (my 24/7 Folding machine): [Build Log] Project White Ranger - 24/7 Team Competition i7 Folder

I run ithe i7-2700K 24/7 at 4.8GHz (I'm about to bump it up to 5.0 or 5.1GHz tomorrow or the next day), and the temps are incredibly low:




As far as flow, you really should have at least 1GPH, if not 1.5GPH. If your flow is too low, yeah, the water will absorb more heat while it lingers around the block, but if it stalls or doesn't move hot water to the radiator it will never cool and if cool water doesn't get back to the block, then the CPU just heats up.

That is why you will want to be in the 1-2GPH range.

You can use a common spread sheet to help determine what sort of pump you will need, based on your blocks, pump, amount of tubing, fittings, radiators, etc.

You can find that here: Martin's Pump/Radiator Optimizer Spreadsheet

Quote for the truth!

Water cooling is like M&M's ... you can't just have one. biggrin.gif

One of the great things about the MCP35X is that it is PWM controlled, so it will only run as fast as needed, according to thetemp oprofile you set it for. I would rather have a pump that runs around 30% speed the vast majority of the time and still has a huge amount of headroom, than a cheaper pump that has to run at full speed all the time because it is less powerful and/or has no control (and thus provides little to no headroom).

Buy once, cry once.

Here is a great article that explains why flow rates are significant.
