CPU Fan Too Loud. Even the Second Fan Is Too Loud!

[Pubudu Kodikara]

I have a Core i3 Desktop PC. Recently, I noticed that the CPU fan is too loud. I replaced it with a new one. The new fan is also loud. But, the new one goes to full speed and scream loudly at boot and then settles. There's no over heating issues and the CPU seems to be fine. Im using an H61MX Foxconn motherboard. Is it a problem with the board? Do I have to replace it? Any software to test the board for defects?

What kind of cooler You have?

What kind of cooler You have?

A standard Intel Cooler. The original CPU cooler came for the CPU. At first, it didn't give me such a big sound. But now its coming. Just bought a new one... Its also an original intel cooler. It also have the loud noise and its the one which go full speed at boot and then settles.

Going loudly at boot is normal for a lot of machines--are you saying it's still too loud even after it "settles"?

Go into Your BIOS-> find something like Hardware Monitor or similar -> change CPU fan speed to, for example, 50% set temperature limit to 50?C, save changes and reboot.

Personally I advice You to change this stock Intel cooler, for something with 120mm fan, temps will be lower and less noise around ;)

Yep :) Started very recently...

Mine does the same thing at boot, but settles down after the BIOS screen. I replaced my fan with an Corsair H60 water cooler and seems to be a lot quieter plus it's 7-10 degrees cooler than on air. :)

Make sure power saving options like Intel Speedstep are enabled so the CPU clocks down when idle

Double check the heatsink is attached firmly and thermal paste is good

what is your CPU temps at idle in windows??

[Charisma Veteran]

Yeah, people have already mentioned what I was going to suggest--check the heatsink and thermal paste and make sure nothing's come loose or gotten dusty/gunked up, then check what options you have for it in the BIOS. If something just recently changed than it's more likely along the lines of the first idea than the second.

Well as it was explained to me, even though your temps are normal what is keeping it normal is the speed of the fan (to increase cooling). Higher fan speed = equals more noise = what the computer needs to keep it at that temp.

There could be other environmental issues going on, improper heat sink conductivity, lots of dust, or decreased air flow in the case either by obstructions in or around the case or putting it into a sealed cabinet or a cabinet that has no air flow.

Computers need to breathe. Even water cooled needs to breathe, although they require less fan speed to keep them cool which means they are generally quieter.

[Hum]

I suspect your room is very warm, and the cooling is not enough.

I would leave the case panel open -- use a floor fan if you have one.

[Pubudu Kodikara]

There's no dust... I have cleaned everything! The temperature is normal... I have even used a new thermal paste. With the old fan, the cpu temp went upto 65C recently with the loud sound. Then I applied a new thermal paste and the heat came down to 37 to 45 C. Now for the new CPU fan also I used a new thermal paste!

it means your cpu is heating up and the fan increases speed to cool it down. you probably need to redo the thermal grease.its probably cooked.

Re added the grease :( Is it a problem with the CPU or with the motherboard?

I did it... Now through the HW Monitor (From CPID) I can see the temp is between 31 and 40. Now the fan is becoming loud and then going normal... increasing and decreasing....

When Your CPU temp rise then fan speed also rise. Quite normal. Change this cooler, for some about 29$ you can get http://www.newegg.com/Product/Product.aspx?Item=N82E16835233082 Gaia, quite good cooler and not expensive, set fan speed under 1000rpm, Your temps will be under 30?C in idle.

I was use this cooler with my i52500k OC to 4.4 GHz and under OCCT I've hit maximum 69?C on hottest core.

XIGMATEK is awesome. I've used them for nearly 5 years. Very impressed. :)

Will it be too big for my casing?

Post Your case name please :)

No problems, will fit perfect fine :)

Same cooler in same case ;)

Is it warmer or more humid in your house than usual? Anything changed environmentally?

Moved to a new house :) But the new place is a bit colder than the earlier one!

Also buy some good thermal grease, like Zalman STG 2 or AC MX-2, this thermal compounds are best for relative small money ;)
