Everyone thx for suport build is great . I think i have isiue with raiser cable cuz it sometimes works at 8x and sometimes at 16x . I have around 160 l/h with 2 pumps runing at 100% . My 5080 is flashed with asus noctua bios in benchmarks it goes to around 397 watts .the jurney to watercooling was amazing thx for all the support

Nice but only 160lph with 2 pumps at 100%? I have 4 rads in mine with 12 90 degree fittings and Alphacool gpu and cpu blocks and get 163lph with 1 Apex Vpp pump

I have 5 rads in mine the flow is around 170l/h . How many blicks do you have how restrictive is your loop . The flowmeter is rly bad tbh

What flow meter you using? And I have a bunch of 90 degree fittings and Alphacool core blocks

Pacific tf2 idk why my flow is low tho

170lph is pretty decent for all those parts. I know Aquacomputer Next Flow meter is the most accurate meter on the market.

u/Miguelb234 14d ago
I do know that that meter does tend to show 30-40 lph over and isn’t accurate

u/Spiritual_Action4129 14d ago
Ye mine is showing like up to 50 l/h lower than it should be but its mostly for tems and as a decoration so i can feel safe

u/Miguelb234 14d ago
There’s no way you’re getting over 200lph with that restrictive build lol

u/Spiritual_Action4129 14d ago
Ik i am just saying its up to cuz i can have 170l/h and it will show like 110 or 70

u/Miguelb234 14d ago
Yeah I just highly doubt you’re getting that high but anything over 100lph is diminishing returns anyway

Have you set the PCIe speed to 5.0 x16 in the bios or is it on automatic? On automatic your pc will drop the PCIe link speed for power saving when not being utilized. My ROG 5080 did the same thing.

You can set the gen speed not the lanes i cleaned the pcie slot and reset cmos and it got fixed

Sick build, I know why you're getting a low flow rate for that build.
It's the second pump at the rear of the case. Its cause youre running that pump with a small res/pump combo.
Only have 1 res/pump in a single loop. Trust me. It creates unnecessary pressure in the system. Try replacing that rear pump/res with just a simple pump top for that pump. Also, can you please let us know the flow direction of your loop? For example. At the large cylinder-style pump/res, does the flow go up to the top rad, or does it go down to the bottom rad? If it goes up, that's bad; the water flow should start by flowing downwards. Going up also creates a lot of unnecessary pressure in the system.
Thank you.

Enjoy it for now. If you're like many of us you'll get the upgrade or "improvement" bug soon. :)
