Pumping UPWARD?

post #1 of 6
Thread Starter 
I have a loop where I start in a dual bay reservoir/pump. My planned route was down into a 480 radiator, across into a 360 radiator, and then up into my dual GPUs (using a dual parallel connector) and then up into the CPU and back over again. I'm certain that I have enough pumping power, but is it okay to pump upwards in this fashion?

Since it's a closed loop, gravity pulls up with just as much force as it pulls down with. Do what works for your loop as long as the pump is below the reservoir for air bleeding. Air bleeding is usually easiest when the water is pumped upward too.

This, agreed - pretty much every loop will be pumping against gravity at some point, and it's closed (hence the weird "gravity pulls up" visual). Like Electrocutor said, as long as your res is feeding your pump, then thumb.gif

What type of pump? I would imagine that you are absolutely fine regardless, but it may help more experienced members to come to a conclusion. I am setting up the loop in my Switch where the pump is "pumping up" almost completely (down to a UT60 240, then up to GPU, up to EX420 in roof, to CPU, then down to res) and I am using, for now, one MCP35X which is more than strong enough. I do have two brand new MCP35X pumps, but I didn't know that spending the $60 on the MCP35X2 Housing would be all that beneficial at this point, so I skipped it (may still add the second separate from the first, but I am getting the housing eventually).

Another thing that would be helpful to know is what blocks you are using as well as the specific rads. Considering how much they can vary in terms of restriction, it's possible that one setup may be excellent in such a configuration while another suffers significantly.
For example, the Black Ice Extreme rads are significantly restrictive, about as much as a good-flowing CPU block! On the other hand, Alphacool NeXXos UT60 rads have such low restriction its almost immaterial assuming you don't have 20 of them. CPU blocks vary even more, with some being extremely good flowing blocks (Raystorm), some having a moderate amount of restriction (Apogee HD), and some being so restrictive they practically require their own dedicated pump! GPU Blocks vary as well, but not as much as CPU blocks when talking about the same GPU, for example the difference in flow between the Heatkiller, Aquagratix, Razor, and Koolance GTX680 blocks is not very significant, although EVGA Hydrocopper blocks seem to be the exception in that they are always the most restrictive blocks available (I would never buy one personally, not just because of restriction but because Heatkiller blocks are works of art and nothing beats German engineering for the marriage of form and function). And of course, RAM blocks will always be extremely restrictive, and while motherboard blocks are also restrictive, they have gotten a lot better and I actually would say that they are worth the money to anyone overclocking more than just a little bit (I can't wait to get the MIPS Rampage 4 Extreme block, it's fantastic looking, but also functional as cool VRMs and MOSFETs can make for a much more stable OC; and this is one reason I got the Apogee HD, for the parallel line abilities).
All of these things have a great effect on whether or not you have a pump that can push through the loop and deliver a fantastic flow rate (1.5GPM), one that can give a good flow rate (1GPM), one that tries with all its might but struggles to deliver anything more than a "yes, the water is moving, somewhat" flow rate (0.5GPM), or even a pump that is simply way underpowered and results in 0-0.4GPM which is so slow that you will have terrible temps.

Thanks a lot for that help! I'll be sure to post more tomorrow and +rep as I'm currently on mobile.

I have a dual-bay reservoir and the pumps are included so bleeding is somewhat of a pain anyways, but it works well. I have two MCP35x as well. I will be using them both. My radiators are somewhat restrictive. I have a Black Ice GTX 480 and 360 at the bottom of the case. They pump upward into 2xEK FC 580s which goes into an EK CPU block and back into the reservoir/pump.

I'm hoping 2 pumps aren't too much power?

Two MCP35X is exactly what I would use smile.gif
