Does my pump have sufficient power?
Does my pump have sufficient power?
Ok so, I'm planning on water cooling my PC real soon and so far I have found all the parts pretty well, except for the pump and the reservoir. Originally I was going to get a Thermaltake D5 Reservoir-Pump Combo except they only have the 300ml reservoir size. I would much rather prefer a massive, over-the-top 600ml Thermatake T33 but unfortunately they don't make a pump-reservoir combo for that size. I'd be willing to settle for something a little smaller like a Thermatake R33(500ml) or an EK-Res X3 400(400ml). Also, note that there is a 400ml pump-reservoir combo called the Enermax Neochanger but I've read from the reviews that it is pretty bad and about 30% of them fail after 2 months, so I'd rather not risk that and I would prefer to buy from a more well-known brand. The problem is that I've only seen one pump used to power massive loops with massive reservoirs like the T33 and that pump is the Thermaltake Pacific P1 which is like 250$ which is way over my budget (i'm looking for something around 100-150$). So my question is whether there is different pump which can still push the water through my loop, or will just a regular EK Revo D5 do the trick? My watercooling specs are: Thermaltake Core P5 case, using PETG 12/16mm, EK HDC fittings, EK Cryofuel Azure Blue coolant, Thermaltake Pacific RL480 radiator, a Phanteks Glacier C350i cpu waterblock for a 7700k, a Phanteks Glacier gpu waterblock for GTX 1070, and at a later date, I might potentially extend the loop into my motherboard (an Asus Maximus Formula IX) which has a built in waterblock. Also when I do find the right pump for my system, I would like to attach it directly to the bottom of the reservoir so its not separate. Do any two pumps and reservoirs just screw together, or is there some special fitting I could use, or will I just have to keep them separate and just connect them with two more fittings and some more PETG? Thanks,

Thermaltake Pacific P1 features a D5 pump identical to the 300ml model you referenced earlier. The same pump is also used in the EK D5 Revo. All these pumps are essentially the same, differing only in branding and reservoir design. The main variation lies with the Enermax Neochanger, which resembles a VPP755 style but offers slightly higher flow (D5 is 655, 755 is an updated version). I might be mistaken about this one... it could belong to a different series altogether. I reviewed the Neochanger for Tom's and found it to be a solid pump.
Reservoir capacity isn't related to pump size or performance—it merely stores more coolant.
I'm looking for clarification on whether my pump is sufficient for my setup. I've been trying to assemble a water cooling system and so far everything seems in place except the pump and reservoir. I was considering the Thermaltake D5 Reservoir-Pump Combo, but it only comes in a 300ml size. I’d prefer a larger one like the 600ml Thermatake T33, though they don’t offer a combo for that capacity. I’m open to smaller options such as the Thermatake R33 (500ml) or the EK-Res X3 400 (400ml). Also, there’s a 400ml pump-reservoir combo called the Enermax Neochanger, but reviews suggest it’s unreliable—around 30% fail after two months. I’d rather avoid that and go for a more reputable brand. I’ve only seen one pump used with large reservoirs like the T33, which is the Thermaltake Pacific P1 (about $250), far beyond my budget of $100–150. So, am I sure there’s another pump that can handle the flow without issues? Or will a standard EK Revo D5 work? My system specs include a Thermaltake Core P5 case, PETG 12/16mm tubing, EK HDC fittings, EK Cryofuel Azure Blue coolant, a Pacific RL480 radiator, a Glacier C350i CPU waterblock for the 7700k, a Glacier GPU waterblock for GTX 1070, and possibly extending to my motherboard later. I might also connect the pump directly to the reservoir bottom instead of using a separate one. Do different pumps and reservoirs just fit together easily, or do I need special adapters or extra materials? Any advice would be appreciated.
Thermaltake Pacific P1 uses a D5 pump, identical to the 300ml model you referenced earlier. The same pump is also used in the EK D5 Revo. All these pumps are essentially the same, differing only in branding and reservoir design. The Enermax Neochanger stands out as a VPP755-style pump with slightly higher flow, though it might be a different model altogether. I may be mistaken—I could be looking at an entirely separate line. My review of the Neochanger for Tom's was satisfactory.
Reservoir size doesn’t affect pump performance; it merely stores more coolant. Radiators are among the least restrictive parts in a water cooling system, so large radiators don’t hinder flow. Restrictions mainly come from tight bends and overuse of fittings.
In short, most pumps you’re considering are essentially the same. Share your loop components and I’ll advise accordingly.
