Gives significantly better CPU cooling, which is worth it for that little IMO.
It's the reason I went Ncase M1 over A4-SFX.
Now if only the Zalman extremes were still in production.
I know it's on the white label on the brown inner box that the SF-600 comes in. I don't know if it's on the SF-600 itself, I'll need to look when I get home.
Could you do me an enormous favor and read off the Lot code number for your SF600 please?
The original SF600 and the Replacement I just received from Corsair both have bad fan curves.
It sounds like a banshee/290x when I'm running it and full load, then stop the stress tests and stop the fans.
Does your SF600 spin the fan up and down at idle?
This is a bit of a wierd question, but can anyone tell me the lot number of their SF-600 that works properly and does NOT turn the fan on at idle?
Both the original and replacement SF600 I got from corsair turn the fan on and off repeatedly at idle (kill-a-watt reports 40W at the wall).
I swapped it out to a C14S, so no pictures.
There were no other fans in the build, due to the duct (the U9S itself forces air out of the case due to positive pressure, while always drawing in cool air).
No, but considering the GPU runs at 94C....
It would have just sucked in the exhaust heat from the CPU.
Mind you I'm running positive pressure for dust reasons, I could run negative pressure and it's FAR easier to do and cooler internally.
Something's wrong. I ran a U9S with one fan, and it...
I have a 290x reference blower (was using CLC in full tower, reverted it for M1, waiting for Vega), and I just created a duct down to the bottom intake using some painters tape. Doesn't heat up the case because it's a closed system.
Air in from the bottom vents, into blower, out rear of case...
That's what I thought, but the fan's supposed to stay off until like 120W, it's turning on at 30W repeatedly....
I just bought it, but it was from Fry's which probably has low throughput. I'll probably just RMA it...
My SF600 doesn't buzz, but it's brand new and the fan curve MUST be wrong.
It spins up and down at idle (30W measured at wall) and sounds like a fucking 290x blower under 400W load
Confirmed, I redid the conductonaut.
[email protected]@1.41V, conductonaut under and over IHS, Ambient 75F, fans locked at 100%, Prime95 small FFT (non-avx), OPEN-AIR
C14S Fan on top blowing down: 74C
C14S Fan under blowing down: 77C
U9S: 84C
The U9S is initially the same temps as the C14S, but...
Near ambient, considering 1.24-1.28 is the stock VID range...
TBH it wouldn't be worth delidding...
Another question, is my SF-600 Defective? It's spinning the fan on and off at idle power (30-40W at the wall with a kill-a-watt meter).
This is what I used previous with a CLC on the video card. If the video card is a normal flat style cooler (dumps hot air in case), I'd rather just positive pressure the whole case rather than draw hot air into an already highly OCed CPU.
That is in fact the plan when the M1 gets here, as ducting it basically guarantees the same temps as open air (as it draws outside air directly into the cooler).
The question is whether to try the C14S again inside the case... it would fit, but I'm not sure the cooling would be worth it.
I just stuck the A14 on top for maximum cooling. Both were open-air test-bench tests, which benefit the C14S.
What did you relid and with what, and what voltage and temps are you running?
And is that inside an M1 with the case side on?
I rescind my statement about the U9S not holding up:
Delidded conductonaut relidded 7700k [email protected] w/ Gelid GC-extreme, ambient 75F (p95 non-avx small FFT) after a couple minutes:
C14S: 80C
U9S: 82C
The U9S is quieter, and that's in open air, and the U9S will have a massive airflow...
Good news, the Noctua C14S (Stock A14-PWM fan on bottom) fits with an ASRock Z270 fatal1ty ITX... with higher than normal profile RAM....
7700K at 5.1Ghz (+130mV offset, High/Level1 LLC)
Delidded... obviously. (Not bare die, as that would not post, but Thermal Grizzley conductonaut (liquid...
So a REALLY weird thought occurred to me.
What if you tilt the mobo and GPU at a 45 degree (or at least diagonal because of the backplate area) angle.
GPU behind the mobo, enough space for a U9S?.... SFX could be mounted opposite (right=left) of where it is in the ncase M1...
Maybe I'm just...
I prefer air tbh.
I've used all the cooling methods, and custom is reserved for absurd clocks on gpus, and CLC is good when you want to do low case airflow and dump heat outside the case, as well as use negative pressure to reduce the overall number of fans.
Air + ducting is what I've settled on.
Forgot cable hadn't gotten here from china.

SATA-Express is PCI-E x2 electrically, so that's valid.
M.2 would be better, but this isn't a GPU so it doesn't need the extra 2 lanes, so I didn't bother.
Mobo is...
I just got a Z270 ASRock ITX Fatal1ty, and the board is fantastic.... other than the fact it won't post with anything in the DIMM A slot.
DIMM B only works great, DIMM A, nope, DIMM A+B, nope.
CPU fan whirrs up and down kinda pulsing at high rpm.
