System fan error on g62-352ca on startup. are there two fans ie a cpu fan and a system fan?

I get a system fan error on power up? Are there two fans in the G52-352CA? Ie a general system fan and a CPU cooling fan or just the one CPU/heatsink fan?
If it is the CPU/heatsink fan then there are 4 part numbers for different options. Is there some way to tell from the model number or features as to which is needed. I would prefer to have the part in hand before opening everything up. Are there better fans to buy and if so how do I find them? This unit was always running a little on the warm/hot side,

Hi,
Could you add the error message to the next reply?

System Fan(90B) error...

I bought an HP 630 Notebook PC one month ago. Now, when it's powerd on, it's showing an error message like "System Fan is not working correctly System Fan(90B)". Though my laptop is currently working but I suspect, soon it will be in trouble due to overheating and it may damage the processor. What is the permanent solution for this problem. I don't want to keep my laptop away for days. Please help me as soon as possible...

Thank you for any help you can provide in this situation.
Hi there
I think you have to go for replacement cooling fan/heat-sink assembly otherwise it may damage your board, processor, card etc.
Before that please promptly follow the steps given in this document -- Cleaning vents and fans on the laptop & troubleshooting steps:

K8N Master2-FAR - System fan shows 0 rpm ???

Hi, I just got the K8N Master2-FAR and equipped it with two dual core opterons 265 and 4gb of dual channel ram.
My biggest problem right now is that all the system fans are running at full speed, though the hardware monitor in the BIOS show 0 rpms for them?
At the same time my cpu fans are blowing at about 3600 rpms even though their temperature is only about 36 degrees C...
It sounds a lot like a jetplane, and I'm worried the case will start flying
- what to do, what to do???

Quote from: Djernis on 02-April-06, 18:15:14
I've got the system fans fixed now -Faulty wiring... my own fault
However the speed of the cpu fans are still running 3600-4000 when they are idle at about 36-37 C ???
like what i have said, u can use speedfan to control it..
@admin, soory for using msn stylo....

Question about heat & system fan ? with Corecenter software?

hello guys,
i am having some strange experience well i just happened to clean my CPU well just external clean with cloth well then when i started i heard sound of some sort it turned out to be a plastic piece with the fan anyway i just did not do anything else well recently my CPU is very running cool i mean does System temeperature goes high will my CPU fan go high too i mean i dont' get a reading for my System fan speed in corecenter why ? can i do something about it please tell me. ? should i check the inside of my CPU well i am no expert but i am still ameteure well what do you say

I don't think CoreCenter uses the system temperature to control fan speed.
Is your cpu fan still working? When you say a plastic piece is broken, do you mean a fan blade? If so you should replace the fan.

How to control system fan

are there any programs out there to control the speed of the system fan, or am i stuck with what the motherboard wants?

I love my reobus . I have 6 fans all controlled from 0-12V. I run them a 7V all the time but it is nice to have the option to go higher if need be.

System Fan (90B) Error / HP Pavilion dv7-4060us

Hi. I have a Pavilion dv7-4060us notebook, Windows 7 Home Premium, 64-bit. I had an overheating problem not too long ago that caused my notebook to shut down on it's own. I bought a cooling pad to help with the overheating, which helped. But now, everytime I start up, it gives me a black screen reading "Operating System has found that a cooling fan has stopped working" or something similar. The error code was "System Fan (90B)." How do I get rid of this error message? Post back here or reach my email at [email protected] Thanks.
This question was solved.

This PreBoot Diagnostics that is indicating there is an issue with system fan. It would be a case of System Fan not running or running at slower speed than it should...
I would suggest, try doing power drain, by disconecting AC adapter, removing battery and pressing the power button for few secs... if that always you to boot to the OS, that Update the BIOS if not than I would suggest contacting HP Tech Support for getting your unit serviced...

2 System fans on the MSI Intel 845PE?

Hello,
I've just built a computer with the 845PE Max2-FISR, and want to install two system fans in the case (in addition to the CPU fan and the fan that comes with the mainboard). If I read the manual correctly, there's only one pin connector for the system fan.
Does anyone have experience with installing 2 system fans with this board? Can I splice the two together, and will the mainboard be able to provide enough power for both through the one connection, or should I be considering another solution?
warning, I'm a newbie at this, so I may have some of the terminology wrong.
Thanks,
Matt

Hi
I have installed 2 fans in series and connected them direct to the power supply by making up a lead with 2 sockets and one plug. This is a very quiet solution.
It is possible to connect the hall effect sensor to the motherboard to read the fan speed but you must use the correct fan. Dont live in hopes about reading the fan speed on this motherboard which has problems which are well documented in this forum.
I have tried PC alert and speed fan 4 but can only read the cpu fan and system fan speed in the Bios. (WHEN are MSI going to get round to fixing this.
An alternative would be to use a passive heat sink on the northbridge (Zalman) to make a fan socket spare. (Has any one tried this)

System fan replacement

Hey, some advice needed here. My system fan ground to a halt a month or so ago, a friend gave me a spare fan which came off a board which had died on him. Not long after that fan started slowing down, what im after is a decent replacement.... ive taken the old fan off and have glued a cheap graphics card fan directly to the heatsink, its doing the job.. not quite as good as the original but temps are low, however between the fact the fan looks ugly and that it dont work as good as the original i want to put something better on, ive thought about using a Vantec iceburg as it looks nice, any suggestions?
thanks

Just orderded a KT4V-L - system fan question

Building first PC. Dowloaded the KT4V-L manual and I can only see two fan sockets - one for heatsink fan and one for a system fan. I would like to add two system fans (one at the front of the case and one at the back) - is this possible?

Thanks. Is it just me or this forum really slow when changing page, sometimes even timing out?

DV6-6060sa Do I have discrete graphics memory or UMA graphics memory? + Where is 'System Fan 'B''

Hi There,
I am going to attempt replacing a fan on my Pavilion DV6-6060sa Laptop, I have been looking around on the net and have just now read through the service manual to better understand which component needs replacing.
I am going to be changing system fan 'B', as the error message states at start-up. (I have tried compressed air spray through the air vents but this has not worked.)
In order for me to purchase the correct part number I need to know whether I have Discrete memory or UMA memory.
As stated above I have a Pavilion DV6-6060sa unit, the below snippet is from the service manual.
(12) Fan/heat sink assembly (includes replacement thermal material):
For use only with computer models equipped with ATI Mobility Radeon HD4650
graphics subsystems
518435-001
For use only with computer models equipped with graphics subsystems with discrete
graphics memory
512837-001
For use only with computer models equipped with graphics subsystems with UMA
graphics memory
512830-001
Could you let me know which part number I require, and also send me a link for an original HP replacement part please?
The fan I will be replacing is the fan closes to the power button, looking down at the laptop from a birds eye view it is located on the upper left corner. The two vents (one on the left and one on the top) usud to have air forced out from the fan, which is now not working. I take it this is system fan 'B' and is the heat sink?
Please can you confirm the above information?
Specifically Including a description of which fan system fan 'B' is? (thank you)
I appreciate your help, Simon.

Hi,
90B is the error code, not the location of the fan.

System Fan 90B Error Message

Hello, I've had my Envy dv7-7320us for about 2-3 years and Just last week my notebook shut itself off in the middle of me working on it. When I turned it back on, there was a black screen that read ...... The System Fan <90B> message that everyone here seems to be getting. I sent it over to a computer shop and they cleaned the fan (it was filthy), and I also gave to ok to replace the fan. So they did that as well. Here we are into the 7th day since the error page occured and the shop tells me that the message STILL appears , even after cleaning and replacing the fan. I dont want them to do anything more , because it sounds like things might get costly and if it's something that I can do myself, I would prefer to just do so. Does anyone know why the message could still be appearing , or what other methods I can take to resolve this problem? I just dont want them to do anything drastic or costly for no reason. PLEASE HELP!!

Some bios's have a error message section that needs to be cleared before the message will stop. If not try clearing the cmos by removing the cmos battery for 15 minutes.
