PCGK33 Fan Issue

Hi, I have what I believe to be a fan issue but I'm not sure if it needs to be replaced or if there's something else going on. My laptop is nearing 3 years old. The fan has slowly started making noise to the point where it is so loud (and very hot coming out the side vent) that I feel the need to immediately shut my laptop down (even though I know you shouldn't power off like that). I have an extended warranty with Best Buy and they are horrible. It was sent away for a week and I thought the fan was going to be replaced. Instead, they cleaned it and adjusted an internal control. As soon as I got it back, the fan was making noises again so obviously what they did did not rectify the problem. I don't want to use them again but I have to do something. Also, prior to sending it out, my computer was going into hibernation at random but the DC jack was broken at the time so that may have caused some issues.

Any assistance or direction on what to do next would greatly be appreciated!

Re: PCGK33 Fan Issue

Attention Sony PCG K series noisy fans owners.
Do not try to modify/replace your fans, they are running fine.
The noise is caused by the tightly packed dust on the radiator wall of the processor.
open the PC up, when you remove the aluminum cover you should see two black thermal tapes. Remove the one to your left and use the q-tip and vacuum cleaner to remove all dust. Put the tape back together as well as your pc.

Congratulations! Your PC's air circulation has been restored!
The CPU is not hot anymore and the fan does not need to cool it.
As the result your fan is 70% less noisy.
If you changed your BIOS settings to "silence" your fan, put it back the way it was.

If you have any questions, let me know:

Re: PCGK33 Fan Issue

It could be mechanical, BIOS related or software causing this.

What does the noise sound like? A high pitches squeal? A "tinny" noise like metal dragging on metal? A growl? Does the laptop get hot?

This is what Sony says about the fan issue:

  • Please bear in mind that a fan is a mechanical device and that it is normal for it to make some noise. However, it is possible on certain VAIOs to reduce the noise.
  • Please note that reducing the noise will also decrease the performances of your VAIO.
First try the following solution (which does not apply to every VAIO model):
  1. Restart your VAIO.
  2. Press F2, when you see the Sony Logo.
  3. In the BIOS, select Power with the arrow keys.
  4. Select Thermal Control Strategy and press ENTER.
  5. Select Silence.
  6. Press F10 and then ENTER to save the changes and exit.
If the above option is not available in the BIOS:
  1. Right-click the Powerpanel icon in the system tray.
  2. Click Edit/Create Profiles, then double-click Thermal Control Strategy-Performance.
  3. Change the settings to Quiet.

My dell 1550 is not starting it is starting and shutdowning and repeats the same what to do setup is also not working

This sounds like an overheating issue, either the fan intake port is clogged with hair and dust or the the fan no longer works and is instantly overheating. Listen for the whirl of the fan underneath the the laptop. If you hear aloud noise, then it is either clogged or the fan is going out, hitting something. If you hear no fan noise, then the fan is completely out and needs to e replaced, either way, check that particular part and get it looked at.

Won't boot up

Hi Jeremy if you replaced a notebook/laptop cpu fan make sure that the fan has all the connections properly plugged in. The triple beep usually is an indicator for graphic / video issues but could very well be a sensor issue as well. be sure that the connections don't just look like their are plugged in but also that they are properly seated (especially important with the ribbon connections of keyboards etc).

I hope this helps.

The hard disk and/or the cooler fan makes a bad noise

If you are experiencing noise from in your laptop then it can be the Hard Drive or the Fan as you mentioned.
if it is a clicking noise and the system boots up but seems it is kinda slow make sure you back up any personal data from the system possible HDD failure if the system works fine with no problems and there is noise possible it can be the fan.
Does the noise happen every so often or does it happen if you use the DVD rom? if it happens most of the time it can be the fan or if this happens as soon as you turn the power on then it can be the fan, Possble something it in it's way making the noise possible the fan may have gone loose and is touching something else inside the system or just a simple cleaning may do.
Really depends if it will be a replacement Fan then I guess you may need to call Lenovo for the issue, the Fan will be inside the machine and is hard to remove without removing the Bottom Plastics to see the whole inside of the unit.
One suggestin is bring it to a local tech to have it checked if it is just a cleaning issue with the fan or if the HDD is the one causing the noise.
Have a nice day, I hope this helps.

Cooling fan rubbing

Hi there,

If you are not very good with computers then this is definitely a job for a qualified technician. Computer components are very sensitive to static electricity and can easily be damaged by something as simple as touching a internal component.
If you can see any dust in the fan outlet then use a vacuum cleaner to **** out the dust. Apart from that, a service professional is your best bet.

Hope it helps :)

CPU fan issues

The fan may not stay on all the time - its a feature of laptops to help save power. The fan is also variable speed. As the CPU gets hotter, the fan speeds up. When the CPU isn't being used as much and is cooler, the fan slows or even stops. It turns on to full speed when you first turn the laptop on as part of the BIOS system check.

The noise is another issue. You could have a broken "fin" or fan blade. The bearing could be going out. Something may have simply "crawled" inside the fan's output vent. In any case it may be worth your time to have a professional open up the laptop and look at the fan. I have heard a LOT of noisy laptop fans in my day, and believe me it's not the worst thing to put up with.

Sony Vaio PCG-FRV25 Cooling Fan Issue?

I was going to suggest overheating before I read your own diagnosis; Yes, sound like the fan, but you can check by opening up and watching it. Or install temperature monitoring software such as Speefan;
If it is the fan it may well be that there is only one possible replacement - officially. But it is usually possible to cannibalize something cheaper to suit your purpose!

Need to open acer aspire 3620 to replace fan

I believe that the 4020 and 3620 have the same chassis. See if this helps
To the left of the battery there is an I/O cover with 2 screws, then the heat sink cover has 2 screws. There you should see the Thermal Unit (fan). It has 4 screws. Take those out and lift the unit out.
Let me know , curious to see if they are indeed the same chassis.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Qosmio g25-av513 disassembly

Hi Paul have a g25-av513. First disconnect and remove both hard drives and the battery. In the battery compartment there is a small screw you need to remove and in the hard drive 2 bay there are 2 f8 screws that need to be removed as well. In all there should be 17 screws that need to be removed before you can pop the back cover off. When removing pay close attention to the connectors attached to the underside of the back cover. be careful not to pull to hard or you may tear the connectors which are very thin wires. First you have to remove all the screws on the underside of the laptop. The screws are marked f8's and f16's the longer ones are the f16's of course. I have taken mine apart several times already due to a boot up shut down issue which I believe is related to the modem board underneath hard drive 2. It seems that when ever I disconnect and reconnect this board my power shut down issue disappears. If it happens again I'm going to remove i all together and see if that takes care of my problem.

Overheating problem, with fan stopping randomly

If it's overheating it's possible that either there's a problem with the fan, or the fan/heatsink is clogged with dust. If you know how to open up the laptop you can do that and use a can of compressed air to clean it out which may solve the problem. If not you'll have to replace the fan.
