New I5 Fan extremely loud

Hello Guys,

i just got my I5-3570K today. I installed everything and correct. The thing is that the fan is extremely loud on start up for like 2-3 seconds. When I do a cold start, the fan doesn't spin for a few seconds and then kicks in

Not my Video but the same issue http://telly.com/PHRE3

Any suggestions ?

Well are you using the stock cooler? and if that is from a very cold start mate I wouldn't be worrying too much myself as the fan only starts when the heat is detected and from that video the fan got going almost immeiatley after the RAM beep.

I have seen a few AMD cores do that and although I have that same CPU I do have the Intel LC cooler so I cannot attest to what mine does.

Plus it could be just the fan being new of course do the blades spin easly by hnad? If it goes on like that for any length of time the I would start having a good look at it.

By the by after the machine has been running for a while (well and truly warmed up and you power down and then when it is all stopped and power up does this persist?

Thanks for your reply

Yes i'm using the stock cooler but i guess it's normal. It only happens after a cold restart.

Hiyya N now I think it might be a wise move mate to get an aftermarket cooler as the stock ones are very basic - as i said I installed the Intel RTS2011LC on mine but there are some very good air coolers too if you don't want to go that way.

After all the i5 is quite an investment and for the sake of another $100 or so (tops) is it worth it especially if you are going to game or OC?

Just to forewarn you if you ask in the hardware or overclocking and case modding sections you will get a veritable tsunami of advice

But in my mind the one I fitted (95) and the Noctua NH-D14 ($85) are the go and also you will find them quieter too

I fully agree, stock Intel coolers are only useful as a paperweight.
Check you BIOS fan speed settings and enable Silent or Turbo mode or what yours has.

The computer sends the fan enough voltage to make sure it spins up from a dead stop, and then after it is going, it can regulate the volts to something more reasonable. Some fans require more voltage to get spooled up initially.

I agree with everyone here. The stock cooler is worthless. Get a good aftermarket CPU cooler. But, what it looked like you are experiencing is typical for the stock cooler. It should start slowing down about the time you ended the video.

Yep Kelly thats what I was saying in post#2 by the ref to the core detecting heat and then spinning it up.

I suppose it could have even been the motor in the fan may have been a little stiff being new.

Yeah, most systems spin a fan up 100% for a couple of seconds, especially those style CPU fans, just to make sure the motor has enough juice to get going, and then after it is going, it can reduce the voltage quite a bit and it will stay running at a reasonable level. If the fan continues to spin at max speed for an extended amount of time, there is something wrong.

Yep I know mate I have a similar little problem at the moment too, but it is an older machine and not like the OP's nice build so am not too concerned anymore.
