Computer fan is noisy

£0.00 @
I'm looking to get a new fan for my cpu, the one i have just now is a stock fan. Cleaned out all the dust and its still noisy! Heres a picture of the CPU info. http://i30.tinypic.com/qsnsip.j…

Anyone know if theres any decent ones out there that are reasonably cheap and quiet?

Thanks!

Hi couldn't open the picture but is it a Packard Bell? If it is mine is doing exactly the same thing. Hear it througout the house.

Shop around, but I know the Zalman fans are notorioualy quiet!
Maybe try reading some reviews on quietpc.com?

Replacing the stock fan and heatsink will seriously improve noise levels, also worth looking at the other fans int he case to make sure they're not putting your inner case under higher temps.

My 2 cents...

PS. The heat sinks/fans you can buy are dependent on the SOCKET type of the processor (cpu).

This is the general rule, although there are few exceptions where extra heat disperation is required.... blah blah etc etc . . .

You cant go wrong with the Noctua NF S12 although it will cost you around 10ish per fan (well worth it imo)

If you search around youll notice that their air flow vs db ratio is outstanding

If you check the descriptions most of the better ones say what decibel rating they have, the lower the better
#7
Thanks for the replies so far guys, will i need to buy a seperate heatsink?

If so any recommendations?
#8
The type u are after is for a socket 775 cpu , make sure it is the cpu fan that is failing, the psu fans fail much more often, double check
If its not a generic machine it may also have a air duct so make sure your fan will fit with this as leaving it off could make things overheat badly
also on replacing let the system go cold before removing old one and clean cpu with solvent (surgical spirit/meths will do and is cheapest)
#9
I would say yes

For its size / price, the Thermalright Ultima-90 is a top performer. There are a few better performing ones out there at twice the weight (+50% more expensive) but difference is only 1 or 2 degrees tops so not worth the compromise imo. Scan.co.uk usually rotate their daily specials to include the Thermalright coolers so you can probably get one in the £22 - 23 range from them if you can wait a week or so and follow their daily specials

Thats great advice thanks!

My pc does have an air duct aswell, i'm positive the noise is from the cpu fan, 100%

The pc i have is a fujitsu siemens scaleo p.

Pretty sure ive been in one of those, from waht i remember it doesnt use a standard intel fan but uses a generic hs with a standard 80cm fan, try and get a pic of existing setup but as i said think u can just replace with standard 3/4 wire 80cm fan, whoever recommended spending £25.00 on a cpu fan for a i630 cpu not worth that? lol

Thanks for that, can't i just take the air duct out and stick in a new fan and heatsink?

Not a good idea many modern systems are carefully balanced on heat management.air flow and ur new £25 hs/fan could actually cause other things to overheat like your harddrive/mainboard
if ur system is roomy with a decent unobstructed airflow path over the mainboard and there is an accessory fan on rear to remove hot air from inside u could probably get away with it
Also consider checking if ur mainboard will take a newer core2duo chip like the 4500 these run a lot cooler than the prescott u have there and will probably come with a fan if u buy the retail version.
£25 towards a new cpu or just making it a bit quieter u decide ;)

I'll defo think about it ;-)

Heres some poor pictures of my system ( i know its dirty but when its clean its still noisy :p )

Should be ok as it has rear fan.
that is a asus mainboard so checking on compatibility should be a doddle, get the model number off it and check web site cpu compatibility list.

How much would the core2duo cpu cost me?

Think i'll go for the cheap option and get a new fan/heatsink.

I measured my air duct to be 9 and a half cm so the fan should be the same size?

What would you reccomend except the new cpu :p

I should add that my psu is 350w max if that makes a difference.

think u can get the 4300 for bout 50 but shop around
its not the width its the height of the heatsink that will be hard to match
get a new fan of course,
psu requirements would be less with new fan/cpu

Is that product not a case fan?
#19
E2180 / E2200 may do just as well as E4500 and they are both great overclockers. You can get the E2180 / 2200 for about 45-50.

Darren - I have 6 of them in my case, 5 being used for air flow while the 6th is utilised as a CPU fan. You just need to get 120mm fan clips to be able to fit them on the heatsink (if you decide to go with the Ultima 90 - it comes with the required clips)

No problem thanks for the suggestions so far.

I like the suggested fan as all the reviews on it are excellent can you also reccomend a heatsink aswell that would go with it?
#21
Sure - You can get some monsters but having recently built a new rig I can highly recommend the Thermalright Ultima 90 for the sole reason that its half the size of the heavyweights (its still pretty big!) without compromising on performance - 1 or 2 deg. I have the Noctua / Ultima 90 combo in my case and my wife didnt believe the computer was on the first time I booted it up...

Thanks for all the help mate ;)

I'm a bit wary of taking the motherboard off though, most i've done to a computer is fitted ram and a graphics card :oops:

I'm going to bump this to see if anyone else can give me a helping hand ;)

Personally I would remove the tubular air-flow adapter for a start and see what happens. It really won't be making that much difference, probably impeding airflow more than it is helping. I wouldn't be narrowing your options of an alternate HSF (heat-sink & fan) based on wanting to use that hunk of plastic lol.

You could try removing the heat-sink and re-fitting it, perhaps checking the thermal compound underneath to see if there is any and what it is. You need good case airflow rather than plastic fan guides, you should have at least 1 intake and 1 exhaust fan and then the airflow should be good enough.

Looking at the pictures you have no exhaust fan, this is a hell of a lot more important than that plastic tube. I cannot see the front of the case, but if there is no fan their either, you should be looking for 2x80mm silent fans to put in. The one at the front as intake, the one at the back as exhaust. Remove the plastic tubing, and that should drastically improve temperatures thus meaning the fan will run slower and be quieter.

If you want a new CPU cooler that is easy to fit and cheap you can go for this one;
http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=340995

First thing you should be doing though is either getting a new case or getting the airflow sorted out in the one you have. Then look into upgrading the CPU heatsink. Basically, no matter what heatsink you have, if the ambient air temperature inside the case is high because there is no active airflow the temperatures won't come down much, if at all. So your still in the same boat. You need better airflow first.

If you want a new case, although this may or may not be overkill, I would recommend this budget one - great performance, silent etc.
http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=660781
The reason I recommend a different case is because your airflow vs noise will be limited in your current case. Newer cases come with 120mm fan options, basically they offer better airflow at lower db.

If your looking for cheap 80mm silent fans - try these:
http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=700894

Very cheap indeed, less than 21db, good airflow etc, not much more you need.

And you can find thermal compound here: http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=353109

Feel free to PM me if you have any questions about this post - I don't always check these forums unfortunately so it is unlikely I will reply again. Good luck.

Phear, i think that may be a little understated, having worked with a lot of proprietry designs its not always that straight forward
Some times there is no clear air inlet on the front of these cases so removing the air duct can cause the cpu fan to collect warmer air from inside the case making the fan run faster and much noisier
Looking closely at the pictures it appears there may actually be an exhaust fan already but mounted on the outside, OP needs to clarify if that is the case
It would be a shame to be spending 20-30 quid on new fans to show no improvement
#26
If there is an exhaust fan, I still believe the plastic pap should be removed, if there isn't, as I mentioned he should get one, and an intake one also (for the front or the side). From what I understand about airflow, which is not much but enough to realise that, if there is enough drag, air is going to be coming and going quite quickly. Blocking off that hole with that duct would hinder this sort of set-up in my eyes. Putting a fan on the side hole, blowing air into the case, and a fan on the back to blow out would be in far superior to sticking with that plastic tube heh.

He wants to know how to improve the fan noise, basically he needs lower temps for that. Therefore he needs airflow. The only reason that tube is there is because the active airflow is so **** in the case they had to put something there to help it out. So I said remove it, because he should be upgrading it - and upgrading it requires its removal for a good set-up. Keeping that on or being afraid of removing it is going to limit his options for upgrades, this is not what he should be told.

He needs an intake and exhaust fan set-up - then there is no need for the tube. The tube is there because, as far as I can tell, and from what I have seen in the past, there is no active airflow like I am suggesting. There is no intake fan, or there is no exhaust fan, possibly there is neither. Then yes, the tube is making sure the fan is using cold air from outside the case - because the warm air isn't being expelled, or there isn't any air being forced in, then the tube would help. BUT removing the tube to add active flow (in and out) is a much better set-up - hence my condemnation of the tube hehe.
#27
Obviously its the mans choice but I think you missed the point here, trust me what your are suggesting is ok on generic cases but not on these designs, there is no point to your argument because you cannot create a good airflow thru the case without actual vents on the front, and this design probably doesn't have any at least not enough to provide the kind of airflow you are talking about.
For example your suggested exhaust fan can shift what? 30 cfmx2 cos the psu fan will prob shift the same, where is this going to come from?, you could end up with the case whistling like a rabid football ref.
That sure wont help noise levels, without the cold air coming in over the processor its fan will speed up and make more noise, as the temperature in the case rises cause theres no fresh air the psu fan will increase making more noise sorry but to risk spending money without hard facts to back them up is not a "Hot Deal"
better to go with the new case scenario or simply try replacing the generic cpu fan only at a cost of what a fiver
Chances are the noise is from a faulty fan
#28
One intake on the side, one exhaust at the back. Surely possible, it can be seen in the pictures.

Then mount a Freezer 7 - job done.

Of course the case is problematic due to its size and design. But I am sticking by my guns on this one (so to speak, I don't actually have any guns). If he can improve the intake and exhaust set-up the current CPU cooler may get quieter (as the fan could possibly be running at such high speeds, whiningly high, because the temps are high).

If that doesn't work, then he can get a new heatsink. Buying two fans costing around £2-3 each isn't a whack on the wallet, and it will still improve the airflow over the current (by the looks of the pictures) tube plus CPU fan set-up as the main source of intake air.

If the case isn't good enough for a better intake and exhaust set-up, he may as well get a new case, like the one I posted earlier for this reason. A new cooler that is going to make a big difference in temps will likely not work with the duct and the main cooling set-up of the case. A cooler that will work with the duct will likely not give any better results than he is seeing now. This is just speculation of course, but it should be mentioned.

If he can change both, the current airflow loop and the CPU cooler, or just the active airflow, then I am sure he will see a difference. Just changing the CPU cooler may make matters worse, or make no difference at all, hence my lengthy posts. Hope that makes better sense now - not trying to miss your point, just trying to explain mine hehe.

Obviously it is hard to be 100% accurate with the pictures and no temperature readings, but I am not trying to make him spend money for no reason, as I am sure you are not either. I am just pointing out what options he has, and what I feel about the subject.
#29
Theres a small fan on the side, think its to keep the hard drive cool?

Theres no front intake fan or no exhaust fan either. don't want to spend alot of cash just to make the noise level go down a little to be honest.

Cheers!
