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!

    The fan is just running at a really fast pace as if it is overheating. This happens from the time I turn the computer on AND I bought a cooling pad with 2 fans in hopes of cooling it down and that has done nothing. I can't seem to do anything to stop the fan from slowing down everything else on the computer.

    I had the same problem... I have a PCG-K33, and I've had it since 2004... did some research, and suspected that the thermal grease (which makes the thermal link between the CPU and heat sink) has degraded/dried up over time. I disassembled the computer, removed the heat sink and CPU, and reapplied new thermal grease. It also helped to blow out the heat sink air paths with compressed air... lot of dust-bunnies flew out!

    Seemed to help. I also got into using some free software to monitor the temperature sensors in the computer (try typing "Speed Fan" into Google).

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.
Solution:
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:

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:
NOTES:

  • 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.

HOW TO REMOVE OR REPLACE ICE MAKER FAN


No, there is a different error code if the control board is bad or there is a wire connection issue. The IF error is a comon error and either the fan needs to be replaced or something like ice is blocking the fan from moving. Check to make sure ice or frost isn't blocking the fan, and if it's clear, you need to just replace the fan motor.

LG LRFC25750tt Er FF error- we already cleaned out fan. There was no ice buildup on the fan, cleaned off debris and dust. Plug it back in and it works for a few hours and then we get the error code


Hello Nicole;

My name is Peter. I am a retired field service refrigeration technician.

It is quite a task to get to the fan. Did you really remove the back wall and access the fan? If so good for you.

I doubt the problem is the mother board. The problem is your fan, it is starting to go. Accessing the fan is the hard part. Replacing the fan motor is the easy part.

The fan motor is about $50.00. Part number 4681JB1027H.

Where are the numbers on the motor housing hunter Douglas fan to operate remote


Hi there,
I'm not totally sure what you're asking? Do you need the numbers on the fan because of a bad motor, and need information for it? Or, are you looking for information to operate the remote - which is usually found in the owner's manual - which I'm sure you know already. Or, is your remote not working - and you think there's information on the motor to help assist you? Or, are you not sure why your remote isn't working - and think it's the motor? Well, the remote has a transmitter up inside the canopy - next to the ceiling, where the fan is attached too. This is usually the reason why the remote doesn't work - unless you need new batteries. It's always good to put brand new batteries in a remote, because a lot of times - people take from a drawer, cabinet, another appliance, remote, etc...and this doesn't always solve the issue. Without going into the phenomenom of electrical theory, etc. - I'd just try new batteries, if you haven't done so already. Otherwise, you'll need a new transmitter. Now, the way to see if this is the problem - is to turn off the switch (or better yet, the electricity) that operates the fan - and remove the transmitter. Then, reattach the wires directly. You should have one Hot wire (usually colored, but not always the case) - and one Neutral wire (usually the white wire, but not always the case. After you connected the Hot wire to the colored wire of the fixture, and the neutral wire to the white wire of the fixture. Go back and turn your power source back on again. This should allow you to work the fan with the wall switch. If it comes on, then you know you need a new transmitter. Otherwise, there could be an electrical issue up in the ceiling, or somewhere. However, I don't believe you'll have to go that far. Try the new batteries first, then bypassing the transmitter next - and I believe you should have your answer by then. Good Luck, and I hope this will help you...Jim

I have a HLP5063wx/xaa and when I turn if off I hear something like a fan winding down. Also every once in awhile when I turn it on the people are red but i turn it off and back on and everything is


Yes the fan can be replaced but I believe your issue is actually the colorwheel which is going bad which can lead to color issues eventually the set will refuse to power up if the bearings fail completely inside the colorwheel

How to overcome overheating issue in my desktop?


Depends on what's overheating. If it's you processor you have to replace the thermal paste between the heat sink and the processor, if it's the ram you need to make sure it has proper ventilation, if it's the hard-drives the same etc. You need to be more specific.

Hi, every time I turn on the heater of my 1996 gmc jimmy,it's very noisy,there's a rough sound and whistling sound.pls help me to solve this issue.thanks.


Its either something rubbing against your fan motor, or the fan motor is going out. Remove fan from under hood fi\rewall area, check it carefully by removing it and turning it on, inspect the duct area , and you should find your problem. If its the fan motor, replace it. Good luck.

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 :)

Can I use a faster rpm lamp fan ?


If you found a fan that mounts and is the same physical shape and size, I believe the rpms would not be a issue as long as it has at lease the same rpm. If it is higher I believe it will work. You don't want to bypass any wires. But be sure the plug connector wires are right.
Hope this helps,

Blowing hot air, compressor not kicking on, just fan ? ?


are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.
