This review is from: OKGEAR FC444PWM-12 12" 4pin PWM fan Y cable
Pros: Usually works OK
Cons: Sometimes one or both of the fans would stop spinning. Wiggling the connector made the problem get better (or sometimes worse!) Plugging in a fan directly works OK. It looks like there is a bad connection at the motherboard connector.
Other Thoughts: A few months back my computer turned off from the CPU overheating - neither fan was spinning. After paying attention to the fans after that, it looks like one of the fans would stop spinning occasionally, then start back up after a few hours. When both fans stopped spinning AND I was running a CPU-intensive program the computer would turn off.
Gave it 2 eggs instead of 1 since it only completely failed twice over the year I've had it.
Pros: Silent when idle (but see below), low power consumption, high throughput, BIG!
Cons: 1 out of 5 died after 2 weeks. (Not a big issue; that's why I bought 5!)
The others are doing something very strange. When idle, one of them just decided to make a repetitive seeking noise, like it's reading a fragmented file over and over every second. This starts the instant the drive spins up, even when it is not plugged into the data cable. After another day, one of the other drives started doing the EXACT same thing. Now, after a week of that, the second drive stopped doing it, but a third drive started up...
The drives show no other problems - performance is fine, and the noise stops when the drives are actually being used. SMART results show nothing out of the ordinary. It seems to be entirely inside the drive, as though they spontaneously decided to do some sort of very long self-test.
I hope they figure themselves out soon. I don't want to send back any more of these.
Other Thoughts: Took off 1 egg for the defective drive, and 1 egg for the disconcerting things the others are doing.READ FULL REVIEW
This review is from: Rosewill RCW-310 - 12" Dual-Fan Power Y-Cable - 1 Male to 2 Female
Pros: It is very nice if you need to plug one fan into two places
Cons: It's completely useless.
I figured that, since the description says it's a power *splitter* that it would split one power connection to two fans. Instead, this is more of a power *joiner* which powers a single fan from two separate places.
I should have paid more attention to the reviews, and to the part that said "1M-2F".
Other Thoughts: Not only is this useless, it can be fairly dangerous. Since this gives the fan power from two places, they have to be exactly the same voltage. If one of the two fan headers is at, say, 5 volts (due to speed control) and the other is at 12 volts, then this gives a direct wire from 5v to 12v. That's called a short circuit...
I suppose I should be happy that I bought 2. Now I have enough parts to solder an *actual* power splitter myself.
