Nzxt kraken X62

[gasolin]

I bought for my self a presant a Nzxt Kraken X62 with Noctau NF-A14 PWM fans.

When i had the pump on 100% in the bios (asus,ryzen 3600) it ran in silent mode (2000 rpm) so i installed nzxt cam after the kraken x firmware software update there was.

No i could adjust the pump so i would be shure to run at max rpm, performance. At max rpm it's silent, at lower rpm (there are 5% steps), theres a very small difference, i choose 75% (about 2270-2280 rpm) mabye a difference of max 2 db, it's quiet but i can hear it at 100% if i listen to it or there no music,sound from my speakers, for silent freaks it's certainly not loud, just a weak rumble, alot more intrusive having constant coilwhine from a gpu.

I choose different fans to get max performance with as low noise as possible with no more than 1200 rpm, at 1150rpm or so (1200rpm +/- 10%) i thought it wasn't intrusive or sounded bad, so i skipped the LNA adapter so they could run without any limit.

My questions

How good are the stock fans, i haven't tried them but they are supose to be one of the better aio fans.

Would it make any difference,advantage of having the fan connected to the kraken instead of the mb? (having contorl of the fans without having to go to the bios every time i need to adjust the fan speed.

i mean if you already paid for the noctua fans and have no other use for them, might as well just leave them on the radiator at this point. but yeah i would probably plug the fans directly tot he pump over the motherboard.

You still will only be able to manually set the fans to a fixed percentage in CAM as the software is bugged ATM (Ryzen 3 series) and will always read your CPU temp as 50C until they fix it. I would set them to the motherboard and set up a fan profile curve in the BIOS for them based on temperature of the CPU until its patched.

There is a preview version of CAM 4.0 and this shows the right temps for Ryzen 3000. The NZXT stock fans are good, but Noctuas are better.
NZXT 140mm Fans - (up to 1800rpm +/-300rpm, 21-35dBA)
Noctau NF-A14 PWM (up to 1500rpm +/- 10%, 24,6dBA) airflow 140,2 m³/h
I'm using Kraken x62 on 3700X with stock CPU clocks, in Cinebench R20 getting max 70C.

AMD recommends not to use any monitoring Software (NZXT CAM) with Ryzen 3000 to get the low C-States on idle. Now I don't know if CAM affects this when its minimized or it needs to be open on desktop to prevent the CPU from doing so. CAM is needed for the Kraken X62 pump to be able to reach the max 2700rpm, without it even with the pump header connected to AIO pump header on MB it will only reach 2000rpm. I think its better for cooling to run constant max pump and variable fan speeds.

I run Kraken X62 stock fans connected to its own fan headers, controll the fan speed in CAM 4.0 Preview, but my fans ramp up a lot on silent and performance preset. Only when its set to fixed they stay around 780rpm. When connected to MB on standard MB preset, they do the same. Its probably the rapid temperature change on the 7nm die. With auto voltages the cpu doesnt go over 60C when testing CBr20 and over 50C when gaming, but if I would overclock I need the full fan potential to be used. Also I need to use CAM so the pump ist at 2700rpm. Has somebody figured this out? The fans vere alright on my old Intel 4th gen, but this ramping up is very noisy for my taste.

You have several issues of concern here...

a) The Kraken uses a thermally inefficient aluminum radiator; to account for this deficiency, extreme speed fans are required.
b) The pump is weak ... desired flow rated for a water cooling loop are 1.0 + gpm thru CPU blocks and about half that for GPU blocks. Most AIO pumps are around 0.10 gpm, again only fan speed is available to mitigate here.
c) Which NF-A14 ? The 1200, rpm model, 1500 rpm model, 2,000 rpm ? 3000 rpm model ? To maintain fans at inaudible levels, you'll wanna be < 850 rpm ... AIso thermal inefficiences will not allow for that.
d) Fan design rarely impacts thermals to a great extent... however replacing the Noctua fans that come on a Noctua cooler with Phanteks SP models can reduce thermals by as much as 6C at same rpm.

Phanteks PH-F140(XP, SP, SP_LED) Fans: Testing - Phanteks PH-F140 (XP, SP, SP_LED) Case Fan Review - Page 3

e) Fan control on most mid to high range MoBos is better than most AIO stuff. Ofcourse, what comes on the MoBo CD, might not address all of the AIOs monitoring sensors. For example, Asus FanXpert does an excellent job of controlling rpm cycling bu using the ramp up / round down feature.

First thing i wrote was:

Now i must admit i don't own the cooler any more, WHY?

It started to have some deep rumble i found strange.

Temps was often 10c better than my coooler master masterliquid lite 240 in reviews (both with stock fans, lets asume they both are quality fans) but not when i used it.

Tried my old cooler again, while i took the kraken cooler out one strange thing happend, the thermal paste was almost perfect, only at the edges there where marks,signs of the thermal paste having contact with my cpu, theres only one screw i had to tighten so it wasn't difficult to mount it, you just need the amd brackets.

yep the kraken is a big no go imo. get the noctua U12A - it cools better than even 360mm AIO's even the H150i according to LinsuTechTips.

because I trust the testing methodology of LinusTechTips more thantweaktown is why.

Cost saving idea.

You could save $100 (USD) from the NZXT Kraken X62 and get the Enermax Axe 50 in that chart. Use the Noctua fans on it in push pull and have just as good of cooling.

According to thermal testing the Kraken x62 is a good cooler, I dont see a problem in its aluminum rad, every Asetek based design has that type of rad.
