CPU Fan - Running Fast....

wackojackouk

Hi guys

Got myself a new motherboard - ASRock P4i65g. Got my mate to fit it for me so installed the CPU P4 2.26 from my old Compaq Evo D510 and after some shorting issues (extra standoffs now removed) it's up and running.

However I've noticed that the CPU fan is running really fast compared to my previous Dell PC. Not sure if this is the case since connecting the HDD/DVD etc.

Went into Bios and it says CPU Fan is running over 5300 RPM and Chassis Fan at 2500 RPM.

Is this normal and is there any way of slowing it down without doing any damage?

Cheers

will not damage your pc , just make shore the cpu fan is conected to the right conecter on the motherboard

Hi mate

There is only one connector for this on the mobo and it's right next to the heatsink and fan. This was the original Compaq Heatsink and fan though.

Here's the readings from my BIOS when I booted it this morning.

CPU Temp - 28 degrees celsius / 82 degrees fahrenheit
M/B Temp - 22 degrees celsius / 71 degrees fahrenheit

CPU Fan = 5666 RPM
Chassis Fan = 2833 RPM

VCORE = 1.564v

+3.30 = 3.370
+5.00 = 5.175
+12.00 = 12.196

Can anyone suggest a way of slowing it down to reduce the noise as it doesn't seem to be running hot.

Is it a case or changing the heatsink/fan?

Someone also mentioned Zalman Fanmate - is this any good?

ps - Not sure if it makes a difference but the PSU is quite weak - only 220watts

Your original fan may not be compatible with your new motherboard. Speed controlled fans normally have sense and control wire in addition to power.

Can you suggest something that might be better than please?

I've done a quick search on eBay for Socket 478 Heatsink OR Socket 478 CPU Fan.

Something like this perhaps.

I'd just use a PCI slot fan controller if I were you, like this one, to manually control the fan speed.

If the fan can be speed controlled, surely the motherboard would be controlling it.

Cheers dude.

I was looking at the Artic Ice one on there too but a bit worried about the size. This one is smaller so might go down that route then as I know it will fit.

One quick question I notice on here it says "White grease pre-applied" - Does this mean you don't need any Heatsink compound?

Sorry to sound dumb but I've only just started to play with the insides of PC's lol

I guess you can't go wrong for £5 can you

Yes I would assume that's correct. Guess that there would be something to remove before actually fitting to the CPU. Probably more details on the manufacturers website link.

You can buy small resistors which fit inline to reduce the voltage to the CPUfan - you could always just buy one of those (Akasa make them and you can buy them in Maplin, online at eBuyer and all the usual other online PC shops like overclockers.co.uk, quietpc.com... too many places to mention).

Or you could just fit a resistor yourself inline if you're handy with electronics! It'll cost you a fraction of what buying a premade one will cost.
