I just bought a new dell dimension e521 and want to replace its case fan with a quiet fan.
Dell cpu fan 5 pin to 3 pin conversion.
Well worth the cost.
1x 5 pin to 4 pin fan adapter converter extension cable dedicated fan interface conversion line compatible with dell computer pc 4 59 4.
The fan uses a 5 pin connector to plug in to the mother board.
This cable convert the standard 4 pin fan to for dell styles 5 pin latch styles.
59 get it as soon as wed sep 30.
I had upgraded the processor to a q6600 which caused the stock fan to overwork and be louder than desirable.
It is a 120mm fan that blows from the front of the case over the cpu heat sink and ehausts to the rear.
Used to solve the problem that ordinary fan can not be used to for dell motherboard one head is plug ordinary 4 pin temperature control fan support pwm temperature control speed regulation or plug ordinary 3 pin mute fan not support speed regulation.
Find many great new used options and get the best deals for 1pcs 5 pin dell latch fan connector to 4 pin fan adapter convertion cable at the best online prices at ebay.
Free shipping for many products.
The new fan i have in mind only has 3 wires.
Worth noting the case fan employed a 3 pin connector which fit fine into the 4 pin connector this provides.
With this connector i installed a high flow fan and used the dell fan connector on the mobo using this converter cable.
Perfect for adding a standard pwm pulse width modulation fan with a 4 pin connector to a fan port on a dell computer that utilizes the proprietary 5 pin dell connector.
But it only has 4 wires to the fan.
If you can i d just leave the cpu fan header unplugged and power the replacement fan off of a system fan header or 3 pin molex to 3 pin adapter.
