Good deal, the vacant header says "pwr fn" being 3 pin & the cpu fn header is 4 pin as stated earlier, which is now a non pwm fan. I will see about adding the exhaust fan & upgrading the cp... Go to the full post »

Hello folks  :)

 

Some good work done George but as mentioned by JD air lines are not best suited to clean electrical equipment, apart from them being too harsh there is also a risk of moisture being emitted from the hose.

 

The temps do look a lot better now and by fitting an appropriate quality rear exhaust fan you will be able to drop the temps even further.

 

Suggestions include:

 

1: Check the the BIOS to see if the MBs thermal shut down setting has been disabled.

2: Check the MB for either 3 or 4 pin fan headers.

3: Post back with an update.

 

To help with controlling fan speeds as also suggested by JD see guide here 

 

Please note that not all fan speeds can be manually controlled using Speedfan or any other software, typical examples are 3 pin type fans, CPU cooling fans that are controlled by the MBs BIOS settings and the internal fan of a PSU.

You know i saw no PWM info in HWMonitor at all, probably no PWM Fan on CPU or a 4 pin connector on motherboard if i am correct on what i saw.

The bios evidently has no option for thermal shutdown, unless I'm not recognizing the wording for it? It does show fan speed (auto) & the volts ,,,..
I may need some help here to make certain..

The cpu fan, has 3 wires with a 3 pin clip (though the header its hooked to has 4 pins) leaving 1 of the pins exposed.
There is another header (I presume it might be a header for a fan, but not sure) it is a 3 pin header, but I need to know for sure if that is for a fan to clip too, in order to safely add an exhaust fan.

Thank you Both..

Tried searching online for more information on your motherboard, not much luck at all. Also did find your manual but showed no references to the BIOS. Be hard for me to see what you see where to look.

Looked here  http://www.fic.com.t...ct/default.aspx   This is your motherboard and model  First International Computer, Inc. K2MCP61V

 

Since i can not even locate a manual for the board or a picture to go by.

 

Usually 4 pin connector on motherboard is for PWM fans,  Pulse Width Modulation PWM fans can automatically adjust the fans RPM's depending on the temperature of the CPU or even if used as a case fan, controlled by the motherboard. 3 pin are not PWM.

 

 

So if you see a 4 pin connector it should be PWM. One near the CPU Heatsink would be marked CPU_Fan take a close look at the board from inside as other fan headers will be marked sys_fan1, so on sys_fan2. Since you see only 3 pin headers this is o.k. for a case fan. I myself would replace the CPU Fan to a PWM 4 Pin, this is up to you.

 

If want to buy a case fan measure the back opening, sometimes either 80mm on the older ones or 90mm. From pictures i found looks like those sizes. As the non PWM will have a 3 pin connector.

Thank you for all your help, I appreciate it... Thanks.

Yes, 3 pin header is a non PWM fan, meaning wehn used will not regulate speeds (rpm) as temps increase or decrease from CPU or Motherboard. CPU 4 pin connector will do this.

Fan are not to expensive if need help picking out one let me know. Make sure to measure the back of case for proper size, same with CPU fan. Measure them vertically ot horizontally. Most likely 80mm on both.

Your temps have been better, time will only tell if there is no more issues with any hardware.

 

Your are most welcome, again!!
