Cpu fan to slow

Fans, mainly the CPU fan, have a speed control which slows the fan down. This is usually controlled by the BIOS. The speed is based on temperature of the CPU. If it's cool with little load the CPU fan will run very slowly and you won't be able to hear it. On startup all fans ramp up to 100% until the BIOS takes over and slows the fan down.

make sure that you have the right heatsink fan on the cpu

change the fan ASAP, since the zooming noise and the slow performance will affect even the processor and you might end up replacing the processor as well if it persists. So get the fan ASAP and problem will be solved.

old post.
odd symptoms.
the OP never once told the full story
what works good and not.
XP runs? surely it can, 0.4% 2016 run XP world wide and way less now 2018, due to virus magnet status.
do not run XP , and the fan is not XP job.
BIOS runs the fans.
if the PC runs at 56C or so and the fans slow that is normal
The bios only speeds up facts at start,
the slows them and monitors CPU heat and GPU heat
if they rise too high the fans spin up.
this is how all PC run
my fancy desktop has 600rpm fans right now, due to cool running CPU. 4 pin fans can do that magic.

The reason for the fast spin up is easy to learn turned on fresh.
the PC ASSUMES the chip are hot.
say PC parked in a trunk at 120F
the you go indoors and turn it on
so to be safe, it runs them fast (like at BIOS machine code instruction 1 or first. it spins them up then watches CPU temps live. this can take a few seconds to do a scan, see a TREND
if the trend show low, temps, it then uses a PWM fan table in the BIOS, and set the fan speed off that hard coded table)
get that?
now say PC was hot turned on then it slows only if fast fans speeds can lower the CPU temp
then rule 2 and 3 on BIOS CPU temps
if bios does not like say 80C it can turn itself off.
if failing to do that, say fan is dead, learn that ALL CPUs from P4 up
can turn them selves off they HALT.
ALL AMD and intel CPU do that.
ok?

and did you really clean it
is the RAD clean.?

the fan can have dust blocking the air way to the mother board take fan off blow out put back see if it sounds any quieter.

As for the green shroud, I would not recommend removing it. The computer case is designed to correctly circulate the air through the system and safely out. As for replacing the fans you can replace them with anything you like, just make sure the new fans are the same dimensions they come in szies 40, 60, 80, 92, 120, 140 and a newer 200 mm form factor so you can just measure them if you don't know the correct size. Next look at where the fans plug in, if it is a three pin plug then they fan's are kept at optimal speeds via the motherboard and bios. So they are already controlled by heat sensors / thermostat so to speak. If they are 2 pin then they just run full speed usually. For the back fan just make sure it is the right size and pin out. You can hook a 3 pin fan to a 2 pin fan plug on the board it will just run full speed all the time. For the CPU fan buy a combo fan/ sink and just make sure the sink is the same as the existing one so it will fit on the motherboard. You could probably get rid of the green shroud if you went with a really high end fan / sink for the CPU but that's up to you. For the thermal paste it is easiest to put a small blob in the center of the CPU and then use a plastic card, such as a drivers license to spread it out to cover the entire CPU, thinly and evenly. Add small amounts if you need to to cover the entire surface. Try not to have a bunch oozing out the sides although it won't really hurt if it is.

cpu fans are smart fans it works according to processor's temprature. more processing of cpu makes fans speed faster...slowing down the speed of cpu fan may affect your cpu's performance

Increasing of FSB (processor clock) from 10% up to 15%.
from 1700Mhz you can get 1850 Mhz.
from 2400 Mhz you can get 2640 Mhz
from 3000 Mhz you can get 3300 Mhz
but not all mater board allow this do.

Hello niceguy_jes2,
click on this link for the ambulance like sound beep description:
http://www.bioscentral.com/beepcodes/awardbeep.htm

"High frequency beeps while running". "Check the CPU fan for proper operation. Check the case for proper air flow".

First item to check would be CPU's fan speed. To do this, enter your bios menu. Listed there is "H/W Monitor". Open it. Check the fan speed, CPU temperature & mother board temp. Chances are the CPU fan is turning too slow & it may need to be replaced. (No less than 2300RPM's). Average CPU fan's spin at 3000 plus).
Next item if CPU fan is ok. The thermal grease between the heat-sink & CPU may have dried up over time & cause the CPU to get too hot. You may need to remove the CPU & heat-sink assembly. Clean off all old thermal grease from the bottom of the heat-sink & from the CPU. If you do this, do not scratch either surface. Use house hold alcohol on a clean rag & wipe away all old thermal grease. Apply a tiny amount of new thermal grease. Re-assemble & check through bios H/W monitor, CPU temp. One or the other will stop the system beeps.

Good luck niceguy_jes2!
Post if there are troubles.
Thank you for using fixya.

Check the speed of the fan in the BIOS and set it lower, although 58-63c is alright for a CPU (P4 is rated to go up to 70c) you might want to make sure that you have good air flow in your case to make sure the CPU doesn't overheat. Usually you can find the fan control in the Advanced section of the BIOS. You'll also want to check the specs of the fan that you have installed as that will tell you how loud it's supposed to be. You might have to get another fan with lower decibels if you want it to be quieter.
