got a great deal today - picked up 2x Corsair ML120 Pro LED Red for US$10 each. remember when each of this bad boy would be like US$25-30 each? have always wanted a case full of these fans, sure they are not the top performer like Noctua A12x25 but it's not supposed to. The LED fits my build, and the fan is quiet enough as case fans (basically silent from 1100RPM).

so what do I do? stuck both on top of the case naked of course hehe. this is not gonna be permanent that's for sure, but it does help cooling quite a bit. Idle temp dropped by 2C with the fans running at 1000RPM only. haven't ran any benchmarks yet.

Picked up a Sapphire RX 5700 XT Pulse today for a good price. The card is clearly too thick for the X1 but the shroud is super simple to take off - just 5 screws holding it to the backplate. Just want to test if it can run without fans directly on top of the heatsink and it did, admirably.


Right now all 3 fans are fixed at 1500RPM and virutally silent to me. All 3 are exhausting hot air out of the case, creating naturally pressure to draw fresh air in from the side.


Auto-undervolt in Radeon Software, GPU temp reached 93C with ambient of 30C but did not throttle much. Will try to improve it with the next steps. Currently idle at 50C, not too shabby at all.

Next step will be getting a mini 4-pin PWM adapter to get the 3 ML120 Pro controlled by GPU temps, and then figure out what fan can I jam inbetween the heatsink and the side panel. Definitely will take off the backplate for extra clearance and use the shield that came with the Dan A4 as protective measure instead.

A weird thing to note though, I have always let the PCIE setting in bios to be Auto. The Mech OC card works out of the box with the ADT Gen 3.0 that was included with the X1. The Pulse card didn't work at all, further it got is loading past Aorus logo and immediately got Windows 10 BSOD - Critical process died/failed. Swapped out the ADT riser for the 3M Gen 4.0 riser from the A4-SFX v4.1 and everything just works. Hmm.

So last night another enthusiast in my local community pointed me towards these amazing little fan - Scythe Kaze Haci 8cm PWM fans. They are slim fans, only 10mm thick and maxed out at 3000 RPM. And at 6 USD each I immediately get 3 of them this morning.

Here is how I jammed 3 fans into the case haha



Ran Time Spy benchmark, GPU clock boosted to 2008Mhz and yet temp only reached 77C with 3 fans on full blast. Ran the benchmark a couple more times in different configs and settle with 3 fans at 2250 RPM - basically inaudible with the case fully closed.

Since I don't have the mini 4-pin PWM adapter yet (getting it tomorrow), all 3 fans are running off the motherboard fan headers so there's no more header for the bottom fan below the PSU. Also the heatpipes of the GPU is too tall and complete block the installation of the fan above the PSU. And there's the occasional warm breeze over my hand now 😂 😂 😂

Welcome to the next instalment!

So I got the T1 v1.1 Black on order, 1st batch with shipping date of July 24th. In the meantime, what do I do to prepare for it? Getting an EK AIO 240 D-RGB on the cheap of course! Got a good deal that is 30% cheaper than retailer's prices in VN.


Much better temp and lower noise. Will be doing some more testing with it but I think I can let the 3900X loose from ECO mode with this AIO 😌

Got these bad boys in earlier this week. Arctic P12 PWM for less than 10USD each.

Time for testing!
Method: 5x Cinebench R20 runs in Air-con room
Conditions and settings:
  • Room temps: 29-30C
  • Pump curve (C-%): same across 3 runs - 36-20, 48-34, 58-52, 64-72, 70-100
  • Fan curve (C-%):
    • Red & Green: 36-20, 50-36, 60-52. 68-74, 74-100
    • Blue: 30-20, 42-38 , 50-56, 56-76, 60-100
  • Ryzen Master setting:
    • Red & Green: PBO enabled
    • Blue: PBO enabled and Auto OC +200 MHz offset

Results from HwInfo64: the P12 is just amazing! At 1800RPM it just kills the ML120 both in thermal and noise performance. At full load I can't even hear the fan noise over the pump noise!
  • CPU temp: avg. and max temp are within 1C, negligible difference right?
  • CPU power: but the P12 is cooling the CPU at 13% more power than the ML120 (130W vs 115W)
  • Pump speed: additionally, the P12 helped the pump to run 100RPM lower and reduce noise

And this is me waiting for the T1. Too bad the T1 only supports slim fans for radiator and Arctic doesn't make slim fan. Guess I'll be saving these for the GPU mod then.
