5900X, 3090 FE, custom loop in O11D XL

notable computer hardware:

  • 5900X

  • 3090 FE

  • 4x8 GB of Trident Z 3200 MT/s CL14

  • X570 Aorus Master

  • Corsair RM850x

  • completely DIY 24-pin ATX and 12-pin Nvidia cables

  • 250 GB 960 EVO, 1 TB 850 EVO, some 3 TB spinner

  • Aquacomputer Farbwerk 360

(sort of) internal cooling hardware:

  • Heatkiller IV Pro in black copper

  • EK 3090 FE block

  • Heatkiller D5 Tube 150 with vario D5

  • two Heatkiller L-series 360 rads in stainless

  • bunch of EK Torques

  • ZMT!

  • six Corsair ML120 Pro Whites as intakes, three Noiseblocker B12-PS eLoops as exhaust

  • external bypass for system use without the MO-RA

  • a temperature probe is taped to it

external cooling hardware:

  • MO-RA3 420

  • nine Silent Wings 3s

  • Aquacomputer Quadro with plug-type temperature probe on the rad as control method

  • D5 vario with Watercool top

  • separate ATX power supply

  • Koolance QD4s and a random assortment of Barrow and EK fittings

  • ZMT!

I think that about covers it. After four years of using a Corsair 570X case, I could no longer stand it and had to replace it with something else. I wanted to use the Heatkiller rads and the O11D XL is both capable of housing them and sufficiently boring. I have a 360 GTS lying around, but given that I am going to use this system with the MO-RA, I can't be bothered to try and stuff the rad into the side. It's plain not needed and entirely more effort than I am willing to exert.

It appears that remounting the block and using the intended flow direction fixed my GPU-coolant delta of 15-16 K. It now seems to be in the order of 9-10 K.
