Are you sure you are talking about the 9200T here?

Does the back look like this picture? The only vent at the back is the one for the fan... (apologies for the angle)

What other vents are you talking about - the sides?

Yes the PVR 9200T I have two m8

The other vent is at the front L/H side as you look at the box

Yes double checked & double ckecked only off in standby

Are you sure you are talking about the 9200T here?

Does the font look like this picture?

There are no vents at the front on the left-hand-side...

That's the left-hand side OF the front. The vent is on the left-hand side AT the front (of it)...

Huh? (you know it's Monday... )

EDIT: Yes, he means the side vents...

Well, that's news to me (and, I suspect, a few others on here!).

My fan remains on all the time in standby, and always has done. Just been down to check it now. It is whirring away quietly despite being cool, having been put into standby since late last night.

What's the experience of others on this one??

Do both boxes turn the fan off in standby?

They certainly do run in standby! I've got six, and you can't miss them!

The older one with 06 firmware/loader remains on in standby mode,imho the reason it don't turn off is maybe due to some type of conflict with the TIR bug

The new one with 08 firmware and latest loader reads "Duovision" instead of the sting message when turned on and turns off in standby.

I'm going to update my 06 old humax with the latest firmware/loader when I get my null modem cable back off my m8, hes on holiday so unable to test yet

I bought mine a week ago, latest s/w. and the fan is definitely off in standby. Looked through the back and when I put it in standby I saw the blades stop spinning.

this would be great if the fan turns off - i can hear mine in Standby even though the feet are padded. its not enough to really annoy but still audible. its also like a magnet for my little girl who keeps heading off to find the sound

Either you and your daughter have extremely good hearing, or you have a particularly noisy fan, or you are actually hearing the disk. The fan on my Hummy is inaudible from more than a few inches away. However, the disk is audible from the other side of the room. Of course, the disk spins down when in standby, unless it is recording (or thinks it is). Your box is not suffering from the "thinks it's still recording" bug (AKA PiP problem), it it?

Is there a new version of MICOM which might explain the different behaviour people are reporting?

What does MICOM mean?!

Have a look Here m8

No change in the MICOM Martin.

Just checked the 'Hidden Menu' of my new box with latest loader and firmware,and the MICOM is the same as my old Humax 2.03

Ta very much!

I wonder if the fan has changed in new Humaxs.
I don't no how the humax fan works, but I no a bit about computer fans which the humax uses.
Some fans have a temperature sensor inbuilt that changes the speed of the fan, others have an external sensor. Some have no sensor, but the computer motherboard does and it varies the speed of the fan. The humax fan is a 60mm size.

If it’s simply the fan that has changed, it would be very easy to change the old one. Someone posted on another forum a long time ago, pictures of the insides of the humax, the fan wires use a connector to connect to the motherboard, theirs nothing in the way of the fan or the wires. Simply take the top off the humax and unscrew old fan and disconnect old connector.

Old Pictures of the insides of the humax can be found on the PVR World website, direct link to the pictures = http://www.pvrworld.co.uk/forum/index.php?topic=55.0

The fan in the box is just a standard 6cm fan (used in PCs and the like). These do not have the 'inbuilt temperature sensors' (do they exist?) The ones in PCs are controlled by the motherboard - by changing the voltage to the fan you can make it spin faster or slower - so you can control the temperature if you can monitor it. If the Humax is doing this, then it will be on the motherboard/firmware side - not a sensor in the fan.


What I am trying to say is, that if the fan is off in standby - it is the Hummy that is doing it - not the fan. So you can't just replace the fan.

See: http://en.wikipedia.org/wiki/Computer_fan under 'physical characteristics'.

i must have a noisy fan then cos the disk definitely spins down in standby
you can still hear the fan though (hence the hope that the new software stops the fan in standby). I thought it was noisy when i got it (the box vibrates to the touch when running) but then started to use it and now can't understand how i ever recorded anything without it

The different types of fans do exist and are common in a PC.

My computer case came with an inbuilt sensor in the fan, if you look very closely near the blades a very small device is sitting in the air flow, as the computer warms up the fan increases in speed, the fan is advertised as having inbuilt temperature fan speed control.

Another case fan I bought had an external temperature sensor that is designed to be put on a component like the memory and speed the fan up when it heats up.

My motherboard has a fan speed control that works on the heat of the CPU (I use it on the CPU fan that has no inbuilt temperate speed control).

Check out function 2 on http://www.thermaltake.com/product/D...1357/a1357.asp

Look at that very small blue dot near the centre of the fan blades in the link below = that’s the inbuilt temperature sensor

Thanks for the info - I see.

The first looks like it needs a thermocouple input (which the Hummy doesn't have) but the second - if it just needs the 3 wire connector then it could be an alternative replacement for the current fan. Now can we get on 6cm in size?

EDIT: the second fan - what is the 'signal connector to motherboard' wire for?

6cm is often used on CPU's, it also used to be a common size case fan. But as PCs have got faster and hotter, 8cm has also become common. especially in case fans.
6cm is still very common and available in all the different forms of temperaure control mentioned in my previouse posts.

I think we will have to wait for Humaxs response.
Unless someone opens up a new and old humax, unscrews the fan to expose the sticker on the other side of the fan that lists the manufacturer and part number.
