Fitting fan to 5810

Post by andyfras »

Having bought one of the £80 5810s from Turbosat, I decided to fit a small fan to improve reliability, as the machine will be going to a non-techy household.

I had a Sunon 40x40x6mm fan in my bit box. It originally came from CPC but the part number is no longer listed. It is rated at 5V and 0.3W. I didn't want it running at full speed, so I used an 18ohm resistor in series. To connect it I used a short 4 pin Molex male to female, again from the bit box, and soldered onto the black and red pins.

The best position seemed to be the back left hand corner, where it just clears the HDD. I used sticky pads to affix it to the lid.

Even at its reduced speed, the fan is audible, but probably no louder that the HDD.

Good idea to fit a fan as a preventative measure. I'd use ties rather than sticky pads to attach the fan. Your fan looks too small to be very effective. Larger fans would have better throughput although they'd cost a few pounds more.

I was working on the principle that anything that moves the air about is better than nothing. The case does not feel hot, even above the HDD, just slightly warm.

I do have a bigger fan 62x62x15 which is designed for 24V but will run on 12V. I may try putting it under the HDD to see if it is quiet and effective enough.

As Jumbo didn't like my small fan, I've now fitted the larger one below the HDD. The fan is sucking air in from underneath the Toppy.

With an ambient temperature of 19degC, the maximum temperature I have seen for the disk is 45degC according to HDDinfo. This was with one programme recording and another programme time-shifting. The HDD is a Samsung 250GB taken from my 5800 when I upgraded to 1TB.

45degC means that the disk is hot to the touch, but leaving my hand on it is bearable. The case above the disk is slightly warm.

The fan came from RS many years ago, so I just checked if they still do it. There is an alternative listed, but it's horribly expensive. See:

Sadly, I didn't remember to take temperature readings with the small fan.

Is that jumbo looking to see why the ties didn't hold?

No, but I think the fan might have come out of a Jumbo(jet). :wink:

I tried to fit a 40mm fan under the hard drive of my 5810 but in my case the fan spins even when the unit is on standby.
The fan is rated at 12v.

Am I doing something wrong?

That's because you're not using 5.15.09T (with the [Sf] patch), so it's actually still on when you think it's in "standby".

Thanks R2-D2.

I know I have the 'recommended' firmware installed (it was the first thing I did when I received it).
However, I'm not sure about the patch you mentioned.

I will check again tonight and post further details.

This has been bugging me for a few days given that I've been running a 5800 for the last 3 or 4 years with a fan under the HDD without any probs.

Thanks again.

The fan I fitted to my 5800 blows hot air OUT of the Toppy. I did try it originally sucking air in, but got better cooling removing hot air rather than drawing it in - especially if the fan is at the bottom of the case.
