This review is from: BitFenix Spectre Pro All Black 230mm Case Fan
Pros: Build design is excellent. Very rugged and durable.
Cons: Company support horrendous. Absolutely no phone support whatsoever. The fan failed within 2 months of owning it (it still spins, but it is making sounds typical of imminent bearing failure). I submitted a support ticket and after a week have still received no response, and I have no other way of contacting this company.
Their support system also emails you when you reply to your own ticket saying that a staff has responded, when in fact they still have not.
I will definitely not be doing business with BitFenix until they clean up their act.
This review is from: GELID Solutions CA-PWM-02 2.76" / 70mm PWM Fan Adaptor Cable for VGA Cooler Fan
Pros: I searched the internet for hours to find an adapter like this that would allow me to connect any normal fan to my graphics card for use with the Arctic Accelero Hybrid II-120 to upgrade from the stock fan (which is nice and quiet but not very neat-looking). Finally found out that Gelid had just the adapter I needed and that it was available on Newegg! For some reason it inexplicably had an extra $3 shipping charge which seems a bit strange given that items 100x its weight were offered shipping for free, but no matter, I needed the cable.
Cable is quite short but who really wants a super long adapter cable? I was already using a 3-pin extension cable so in my case the short length was perfect.
Cons: PWM function does not work at all. I connected the fan directly to the adapter without the 3-pin extension cable and the problem persisted, so I know it must be the adapter. The original fan plugged into the graphics card fan port works just fine, but if I plug in another fan using this adapter, I can only read the RPM, not change it.
Gelid support nonexistent. The only number available is for their HQ in China. Their US number seems to be disconnected and will not ring through. So much for the "top-rated customer service" they claim.
Other Thoughts: Pretty much useless since while using this my fan is stuck at top speed which is not at all what I want in my quiet, professional build.
Gelid, you really need a US support line.
Pros: I've been running the HX series of power supplies since I bought my first HX1000W in 2009. Since then, I've had one issue with the power supply where Corsair immediately sent me a replacement which ended up being the updated HX1050 model. Since then I've had one more (FREE) replacement (not due to any failure on the part of the power supply), and again received the most up to date model, this one featuring the "zero-RPM fan mode'. SEE CONS.
Overall great power supply, AMAZING warranty backed by a great company.
Cons: Zero RPM mode is completely silent at low-end loads, which is great. This works well for the RM450 I have in my server which is quiet and fan-less 100% of its uptime, I have never seen the fan turn on nor have I heard how loud it could be.
The HX1050, on the other hand, is LOUD. My newly built computer does not reach >30dB even under heavy graphical and CPU load thanks to my water cooling units. However, whenever the power supply decides it's hot, the fan revs WAY up, gets loud and fast for about 30 seconds, then spins down slowly and fades back to quiet.
This is pretty counter-intuitive. While it is nice that the fan will last much longer since it is not running for as much time (this would work inversely if the fan used sleeve bearings as the bearings would get sticky over time if not being used, but luckily these fans use dual-ball bearings). It would be MUCH nicer if the fan stayed at a low RPM all the time and never changed its speed. Then my computer would be quiet 100% of the time.
Wish I had just kept my 2013-model HX1050 instead of asking them for a replacement. That one ran quiet 100% of the time without this new "zero-RPM" mode stuff.
Other Thoughts: You don't need a 1050W power supply. Get out of here.

Yeah. Go get yourself an AX860 at most. A 650-750 will meet any single-GPU system's needs
