Bitfenix Spectre Pro 230mm - Performance is questionable?

post #1 of 12
Thread Starter 
I received a 230mm Bitfenix [Pro] fan which I paid a pretty penny for [$20].

I plugged it into a molex from the PSU, with the adapter provided, and it was super quiet. Quasi-inaudible, and it moved barely any air. I tried it off the mobo header, and it spun at the same speed. Compared to 120mm fans it felt so ... weak.

I was wondering if anyone else had this fan and could care to share their experience with it

This fan is supposed to be silent, and it is ... but it feels so weak, definitely not what I was expecting from a 230mm fan. I'm just trying to determine if I was expecting the wrong thing or if my fan is a dud

To illustrate the weakness of the airflow, I couldn't tell the airflow direction without a receipt

Larger fans do deliver the same amount of air as smaller fans but because the amount of air is being delivered over a larger area, the pressure is thus lower and it feels much weaker.

That being said, I have a 200mm spectre pro in the side vent of my case... it's audible (but very quiet), and actually moves a decent amount of air. You might have a dud but IDK, let other people with the exact same fan decide. I can definitely feel the air coming off mine.

Thanks for responding, that's the kind of post I was looking for

I guess I'll wait for my new build to come in and see how the temps are with 2x120mm front fans vs 1.230mm fans

Well, the included adaptor isn't a 12V. rolleyes.gif

drunken.gif That's the answer I was looking for. Although when I run it off the molex, I noticed the molex only has two connectors, presumably 12v and ground? I didn't notice a difference ...

Also, you used to browse the NCIX forums a lot right? I swear I remember when you were asking for advice on finding a job smile.gif Gratz

The connector provided is a 7V adapter, one cable in the 12V, one in the 5V.
Yeah, most likely me. biggrin.gif

IIRC you live in Surrey? biggrin.gif

Btw I ran it straight off the motherboard header, and it doesn't seem to make a difference ... headscratch.gif

Surrey it is.

Unless your motherboard tells you that connection is running 12V, I don't think their power description is quite accurate for fans.

My motherboard is dated, and I'm currently on Linux and haven't gotten my sensors setup. I'll report back when I get the Spectre plugged into my new mobo

An easy mod moving the 5V to a ground turns the molex connection to a 12V.
