No fan above the CPU

I got a 486 motherboad recently. There is no fan or any thing for releasing the heat of the CPU. Do you think any 486 CPU should have got a fan or something above it and I must add the fan or something on the CPU immediately?

Thank you.

Thank you MorFF.

That is the problem....Where I can find a CPU fan or something and how to set on the CPU :-(

Commented:
Most computer Mags and stores should be able to help.  They're pretty inexpensive an easy to fit.

What 486 chip do you have?  If it's a low end one, you may get away with just a heatsink.  Higher spec will require a heatsink with integrated fan.  Either way, they simply clip onto the top of the CPU.  Heat dissipation is better if you slap a bit of thermal paste between CPU and sink (not always essential tho').

Hi MorFF.

Thank you very much for your help.

I will check the CPU and let you know tomorrow. I just cannot image how to clip the sink onto the top of the CPU which is about  1x1 inch but very thin.

I thought a good CPU doesn't need a fan or sink when I bought the motherboard. Did the person who sold it to me take the heatsink off?

Cheers.

Commented:
The heatsink clips onto the socket (you'll see a small lip at each side) not the actual processor.

The need for a fan doesn't depend on how 'good' the CPU is, it's the amount of power it consumes that generates the heat.  the more power, the more voltage and the more those little electrons are buzzing about.  I've got a fairly new Intel P200 (the business) and it needs a fan or you can do without central heating.  I could run my old 486SX25 24 hours a day for a month and not feel any heat at all.

Hi MorFF.

Thank you.
I have checked the CPU. It is
intel i486TM DX2TM, about 45x40x2mm, when switch on the PC the screen shows:80486DX2-S CPU at 66MHz
What is your suggestion?

Commented:
With it being a genuine Intel chip (they build their chips to a high tolerance) and only 66MHz, I guess you should be OK without any fan.

Hi MorFF.

Thank you for the good news for me. But do you mean I still need the heatsink? I have text the CPU by touching it. It became very hot almost immediately after switch on the PC!

Cheers.

Commented:
If it heats up that quickly, you'd better got for the heatsink.  If you're concerned tho' you might as well pay out the extra couple $/£ for a fan too, to be on the safe side.  Make sure you get one specifically for a 486.

Hi MorFF.

OK, I will go to find the heatsink+fan.

Thank you for reminding me to get a special set for 486 CPU....but why? Did you mean the size? What different between 486 and the higher.

Best regards.

Commented:
yup, different size altogether from pentium, therefore different fan/clip etc.

Hi MorFF.

Sorry for the delay.
I just can not find a heatsink+fan for my 486 :-(
Now I deside to make one myself!! That will be a very high one and without fan ;-)
If you have no comment, I will stop this conversation.

Thank you very much.
