Bykski CPU-XPR-DDC-M CPU Water Cooling Block/Pump Combo - Black w/RBW (AM4 / AM3+ / FM2+ / Ryzen 3/5/7)

So bought this for a sff build which was perfect bc no room for pump and resavoir back in January 2024. First one failed within the month so since it's Amazon I ordered another and returned the faulty one with out having to go through the RMA process. Fast forward here to October 26th and the second one has now failed no warning just not pumping anymore. I'm dreading the rma process BTW. Even if I get a replacement I'm prolly gonna just sell it bc I can't trust it. Looks great (w rgb) and worked awesome (before failed), but I sell these computers I build and I can't confidently put my name on this product. Just happy this was my personal build and not my customers.

Not going to lie I have a smaller atx pc case that won’t allow a normal res/pump combo but maybe could use a distribution block pump combo although might interfere with my fan air flow and temps and wire management; my case air flow is bottom up and allows me to have 2 360mm rad for CPU and GPU waterblock(can’t wait to get it for the GPU). Realistically this is a nice little pump which does use molex instead of sata which is kinda of meh but it work just buy a converter. At lowest speeds the pump does 1800 rpm or 24L/M but at the lowest speed it is pretty quiet. The top of the pump has two holes which one is used for the outlet of the pump and the second one would be a fill port but could put a fitting and use it normal I let you would need slim fitting because it is a tight spot. Then the front is three holes and really if you have an inlet on bottom which is suppose to stop air from mixing but eh. Air gets trapped in it and doesn’t and could cause it to mix in the pump but at as long as the res is over the half fill line it will keep working and does take a hot minute to empty all the air out of the system. The placement of the pump is kinda weird for AM4 and it comes with a new back plate for its own screws or it comes with screws for the normally back plates. You have to put the backplate on then thermal paste or graphine pad like I do and then place screw in with a spring and washer on all four corners. A little annoying but I understand why. Aside from that you could have it be both way where the pump is close the ram(I haven’t tried it yet) I don’t see why not just make sure the ports are really well sealed; I am so far pretty satisfied with it and I have used a lot of Bykski products in the past so far I this is one of my more favorite one.
