Hi there, i recently noticed that my cpu temperature was above 70-71 C and i decided to connect an old cpu fan into a free slot of my motherboard, well, i connected it and it works fine but i wonder, can fans be connected to any 3 pin slot of a motherboard? or is there any special slot for them?

I'm waiting for your answers, thanks in advance

What is your CPU Temperature measuring now – 71°C is way too high – How old is PC – Probably has [Dust Clogging] – CPU [Heat Sink/Fan Assembly] – That needs a good cleaning – for [Efficient Cooling] -
___________________________________________________

[CPU Fan] – should be connected to [CPU FAN] Connector on [Motherboard] –

[Chassis Fan] – should be connected to [Chassis FAN] Connector on [Motherboard] –

[Power Supply Fan] usually is [Internally Connected] & Internally – [Self Controlled] – by the Power Supply, itself –

Generally if you add additional fans – you can connect that fan to the Motherboard – [Power Fan] Connector –
___________________________________________________

You can connect the fans directly to a 12 Volt –[4 Pin] ATX Power Connector – This will keep fan at full speed all the time & you will not to be able to monitor the Fan Speed – but why waste these connectors – when you have 3 that you can use on the Motherboard – And if you decide to use them – then you may as well connect them to correct fan to keep monitoring correct – Because –

The monitoring system is a [Diagnostic Tool], that can be used whenever you have a problem – But if you do not have it connected properly now –It will not be of any use/value to you – whenever you would need its service later –

Then again –

You can measure the efficiency of CPU & Motherboard by – Measuring Temperature & what [Fan Speed] is required to keep in [Normal Temperature] & monitoring [CPU Performance] with [Task Manager] – Increased Fan Speeds would be an early indication of – Possible CPU problem – and take corrective/preventative action earlier –

Another use/purpose of the speed control connectors – is to keep the [Fan Noise Level] down – by operating the fans at lower speeds when maximum cooling is not required – And probably increases the [Fan Life] –
