Best 120mm PWM <£10?

[Remmy]

Ohhhhh, would it be fatal to run 5 fans on 1 header? I asked Gigabyte themselves and they said either of the PWM headers on my board can supply 1A.

It would probably be fine then, but I'd give it some headroom, and it's also slightly tidier not using any of the motherboard headers. I'd personally rather use the adapter, it's not that pricey Also again, I don't know if the PWM versions are rated at the same current, I just read the current off my AF140 QE non-PWM as an example.

I quite like the look of braided cables, even going into motherboard headers But I have to connect that adapter to the motherboard anyway to get PWM. I think you guys have sold me on those Air Series fans though, I might even go for the 140mm's

Oh yeah of course

Still, I'd recommend staying on the safer side, and powering via a SATA adapter.

If you can fit them, might as well get the 140mm variants

Yeah, that adapter I linked to takes power via the SATA power connector and then the 4 pin female adapter goes into the motherboard's 4 pin header supposedly so you have a 12v supply and PWM signal; I also thought you could either have 12v constant power, or the fan header supplying the power but not both so we'll see how well that works :lol: I'm going to have to double check the CM 690 III but if I remember correctly I can fit two 120/140mm fans in the front and at the top, and I'm going to need a single 120mm SP for the rad

No worries mate

Personally, I'd spend the 5 quid more and get the Quiet Editions. They still cool very well, but less noise is always a plus in my book.

I think you guys might have got confused at this point. Yes there is a Quiet and Performance edition of the SP120 PWM but the Quiet can only run very slightly slower whereas the Performance can run much faster. Don't confuse them with the 3 pin versions which have a pretty limited operating range hence the need for voltage reducers.

My PE SP120 PWM's can go from around 800-2250rpm which is a massive range.

Corsair told me the QE PWM's run from around 600-1450rpm, although as with most things your mileage may vary based on the controller. Personally I wouldn't undervolt them but I think they would be ok with it if you can find a 4-pin voltage reducer which would be rare as its pointless. (they don't come with one).

Oh yeah didn't realise that (I don't use PWM fans). So the adapter linked above by the OP will be fine without using any fan speed reducers then, and just plugging the PWM header from the adapter into a PWM header on the motherboard?

Yeah I guess it should H100i's have PWM splitters and they seem to work.

Thanks for that
