Yesterday I received my TRUE copper and a delta 120mm 4000rpm fan to go with it, I wasn't planning on using the fan all the time (rated at 50db) just to see what the max overclock I can get but I had a problem running it at all.

After installing the true and the fan I ran p95 to check out the temps at stock clocks but my system failed after about 1 minute (no BSOD p95 just came up with errors) after changing the fan for one of my antec tri cools my system was fine and I have now achieved a decent overclock which is stable. why would a fan do this to my system? and should I RMA it?

Did you plug the fan into the motherboard?

yep, I tried it in all three fan ports also.

It's probably drawing far too much power. See if you have a spare 3pin-molex converter so you can plug it straight into the motherboard.

would a fan really draw that much power?
I dont have any converters but I will get hold of one and try it, thanks for your help.

That was likely the problem. I'm betting the fan was drawing too much current for the fan headers to handle.

If this was the case, you experienced the best case scenario. It's possible to blow out the headers, or in rare cases, kill the board, by plugging in too powerful of a fan.

wow, I didn't know you could kill a mobo with a fan

Thanks for all your help guys +rep for you all.

agreed, get a molex and plug it in the psu!!

yes it would. don't try to do that again, deltas actually exceed the motherboard's specs of what it will deliver to fan headers. You're lucky you didn't break part of your board.

Yeah, these things draw almost 20W

, WAY more than motherboards are supposed to handle. Needs to be attached to the PSU or through a fan controller.

My one is 12v 3A, does that not make it 36w?

 

[Cepheus]

Most fan headers are designed to draw between 3 and 5 watts, as a reference, yate loons draw 3.6 watts.
This draws between 18 and 24 watts, according to the product sheet

they're pretty badass fans!

I've got a couple of 92mm ones I ripped out of a server 3 years ago, and they move more air than the 250mm one in the side of my case.

The one I have is 120mm and rated at 190cfm, so yes pretty badass.

Holy crap, that is one powerful fan.

And yeah that's 36w.

You shouldn't really have more than 1-1.5A total, over all fan headers, and no more than about .5-.6A per header, to be safe.
