Thermaltake Pacific PR32-D5 Plus 16.8 Million RBG Color Software Enabled (TT RGB Plus/Alexa/Razer Chroma) 5-Speed D5 Pump/Reservoir Combo CL-W280-PL00SW-A

The reservoir is watertight, assuming you make the connections properly, and the pump is quiet on its highest setting. That's the most important things to me. The inlet tube makes sure air trapped at the top of the reservoir doesn't get entrained into the water flow and circulated out into the system. It's a common feature on reservoirs, but some don't have a long enough tube. The mounting is a little clunky, I mount it to the floor of the case and I don't need the vertical mount bracket sticking out the back and making it look part finished. The pump wiring is long and colorful, which doesn't go with the black wiring on the cap. The pump/reservoir comes with a USB hub with another Molex connector, seems like they could have done something to reduce the wiring. It also comes with a micro USB cable for connecting to the motherboard. Fortunately my motherboard has plenty of USB connectors, and I don't need any of the conventional USB headers, so this wasn't a problem. In my case the pump drives water through two water blocks, two large radiators, and an inline mesh filter rapidly enough to keep the exit temperatures from the water blocks down to 10C over ambient. If I need another reservoir/pump this would be high on my list. I bought it on sale, so it was an easier choice at that time.

First, I'll say I do not like Thermaltake. Their software for the RGB is annoying. With that being said, their hardware is exceptional. I have been building PC's and using Thermaltake products for many years. This pump in particular has been in two different builds over the past year and half. It runs strong, is super quiet, and I can trust that it is going to last a long time. In the current machine it is pumping through 2 360mm radiators and no problem with flow.

The ThermalTake DDC pump reservoir combo was straightforward in terms of filling. The installation was a nightmare and the wires coming out of the pump left a lot to be desired in terms of strength and quality. The pump is noisy and getting bubbles/foam in the fluid is way too easy.I've been water-cooling my PCs for a long time (Koolance never let me down) and I've never had a pump fail this fast. This particular pump/res was part of a dedicated loop for my GTX 3080. The only indication I had that something had gone wrong was my video card would turn off after a minute (DisplayPort signal drop) even when in the BIOS. The fatal mistake I made was not setting a shutdown alarm up on pump RPM signal missing. That wouldn't have helped when in the BIOS as there is no way to set that for any of the other motherboard headers besides the CPU related ones. Fortunately the 3080 did not fry itself. I had something similar happen a few days ago that "went away" on its own, so this is not a simple working / not working situation.The moral of this long story is this:Always have a dedicated hardware based flow meter (visual is better than nothing) and avoid products with DDC pumps, like this one.

It's a simple looking combo that I decided would be the better route for myself as this was going to be my first custom loop. It looks clean and I am grateful for the mod kit on the top. The shroud over the pump looks clean. I can't comment on sound other than I never hear the thing run and I have it sitting right around 50%. When you crank it to 100% it makes a lil noise but it's not bad (I game with openbacks and that doesn't interfere at all). It looks good and I like the larger reservoir*I like it's size but Thermaltake could have done a few things different I feel:1. I couldn't make the side mounts work with their p90 case (short of maybe drilling holes in it which I didn't want to do to a brand new case).2. Adjustable speeds for the pump is great but the only way to access this is with a small screwdriver and to get under the pump with a flashlight to spot the lil bugger. Otherwise it works good, just not easily accessible nore to change speeds.3. Lastly I had some issues getting a good seal with at the fitting at the exit? port (the port coming from the pump). While it didn't help the EK extension I was using didn't have many threads but I couldn't get the compression fitting in there due to the fitting coming into contact with the plastic pump cover. So the threads probably only had 3 full rotations to go in which left me with a tiny tiny leak (like a drop every 8-10 minutes) but a leak nonetheless. I didn't want to torque the fitting on anymore since I was afraid of stripping the PLASTIC threads...but eventually with the help of some silicone spray it has sealed things up and a month later not 1 drop leaked.Overall it's a great combo for a beginner such as myself but now that I've dabbled with it I think my next loop will consist of separate pump and reservoir.***Update 5/17/2019***Figured I'd add another picture after I decided to reconfigure my loop. While cleaning everything I ended up breaking the insert for the top feed port that goes inside of my reservoir. I did find a replacement piece (Barrow G1/4" External Flow Guide Adapter) that does the job but isn't as long and also technically mounts externally on the cap. I'm sure if I had reached out to TT support they probably could have helped as well.
