BitFenix Spectre PWM 140mm Case Fan (Black)
There was a problem filtering reviews right now. Please try again later.
- I did not use supplied screws, since my case has rubber grommets and has its own longer screws. Mounting was really easy on an empty case, even with shaky grommets (and problematic with mobo in, but this is not fan's fault, it's the case+mobo design, see a side note below).
- Fan was set to level 7 (I think, or Lev 8) on my Asrock mobo, it spins very fast and though making a kind of a somewhat whooshing sound (air is being pushed, after all), the sound and tone are feeling as quiet enough. My son, 17yo, said he cannot distinguish it from other fans in the case - the case was open and my son stated that in his opinion the fan is very quiet. I was just cross-checking with him.
- Though this is a PWM fan, as I mentioned, I used, for a week, for top (farther/towards rear) exhaust. Closer to the front of the case, next to this Bitfenix, I have a 140mm CM 1000rpm fan. Compared to CM the "hand test" is won by Bitfenix hands down, obviously, due to higher RPM. But I like my case quiet and this does the job of exhausting air quietly enough - check and check. Quirtness is a subjective concept, though. I am a bit "afraid" I have negative air pressure in my case now:) That is to say how impressive this fan pulls air. Good for airflow, I am now curious about its real static pressure characteristics.
(My negative air pressure concern - due to two 140mm 1200rpm generics in front, CM and this BitF on top and one 120mm 1600->@1200rpm rear)
- On a side note, just make sure your fans are far enough from your mobo headers and hitspreaders. In my case it is too close and pressed over CPU voltage cable. I couldn't find slim 140mm fans with 140mm mounting holes on sale for now. In the meantime my CPU displays weird behavior and I removed the fan. I am not sure if this is because of the fan pressing on CPU cable, software or old mobo. Just to say - choose your cases and mobo wisely!;)
- PWM! I have a break-out board that controls all of my fans, and PWM is the most efficient way to do that, especially when you have multiple fans running at a time.
- 1.88mmH2O static pressure with 51 CFM at 22.5 dBA at 1800RPM. Basically they maintain high static pressure and airflow but are very quiet! These specs are very similar to most Noctua's which are twice the price, and are ten times as ugly!
- Quality fluid bearings.
- On all the fans I received the exhaust side has 92mm fan spacing holes. This is awesome if you mounted the fans to a rad (Which these are perfect for) and want to mount the exhaust to another part of the case with different sizing. This added flexibility is very much appreciated!
- The white color that I got them in is very clean and professional, and hasn't faded in the slightest. It also matches most other white computer components very well.
When at idle at 700ish RPM, they are dead silent, and for most basic computing that's when they operate anyway. But when you put on your headphones and start up a game, they're going to keep your components cool and not sound like the jet engine many fans are known for!
The only possible down-side to these fans is the lack of any LED ports; a non-issue for me as I prefer a totally dark room when I compute, but this is still a consideration for those looking to light their computers.
The length of the cable, to me, is actually way too long, but for most people that is probably a good thing as it will allow you to place these in multiple locations without extensions, which I've experienced with Ya-Li, Cooler Master and Corsair Fans.
Bottom line: I recommend these to anyone.
Because of the cooling needs of my new system, it is not silent, but it is not overly noisy either. In a less demanding system, it would probably run near silent.
