HDX overheating and shutting down
Posted by: Geofiz on 09 June 2013
Hi, has anyone else experienced having their HDX (which was working fine for over 6 months) suddenly start shutting down due to overheating? I had left mine on all the time (as with my other gear). Now I have to shut it down after each listening season as it generates too much heat and goes into thermal shutdown on its own. Has anyone else experienced this?
You probably want to have it looked at by an authorized service center as soon as possible.
The only thing worse than overheating and shutting down is overheating and NOT shutting down!
That will happen, but more curious if others have also suffered from this problem.
Been running an HDX for a few years now, and never shut it down. Not experienced any overheating issues.
Deffo contact service and have it checked out.
Do you hear the cooling fan at all?
May be the fan unit has failed?

We've not had any "trends" of units doing that if that's what you mean.
The HDX should be able to run without its fan coming on in normal use - a self contained board monitors the temperatures within the unit at several key locations (hard disc, motherboard, PSU, case temperature etc.) and as any of those get too hot then it should kick on the fan at a low speed. If temperatures continue to rise then it should speed up the fan in three stages and then if the temperature continues to rise then the last resort is that it forces a shutdown of the unit.
You don't say whether your fan is working or not or give any idea of the environment that it is working in (is it on a HiFi rack with plenty of free air around it? Is it enclosed in a cupboard? Is it in a very warm location?) but if the unit is shutting down due to an overtemperature condition and the fan is not coming on then it really does need to be looked at by us or a distributor.
Best Regards

I had mine in 2X 400GB versiona and never had the problem even if i found it always very hot in use or not. Now with the 2Tb version upgraded, it stays "cool" compared from before and the fan is never working anymore ) before it was not the case and it was working very often.
Hi Phil,
Thanks for your comments and yes I was wondering if this was a "trend" of sorts.
The HDX is on a Quadraspire rack on a shelf with 140mm posts, so relatively well ventilated and not enclosed.
Very probable that the fan has failed as I have yet to hear it come on. Out of town at the present time but will have to check this again when I get back. In any case sounds like I will be without the unit for a while as it is serviced.
Other than this, it is an excellent piece of equipment and have recommended to several acquaintances.
Well, the HDX is in to the distributor for repair. Much more serious than my dealer thought.
How hot was it getting? My 2x500gb model routinely runs at 49 to 52 degrees farenheit, which seems a little hot to me. No failure yet, though.
It was hot to the touch, not quite hot enough to burn though, enough to be uncomfortable if you tried to place your hand on the top of the case. The fan did not seem to be working, so when the case became hot the internet connection would then be dropped and hence control with an iPad would not work although you could still control it via the touch screen. After a further period of maybe an hour or more the display would freeze. Restarting the unit when the case was still hot to the touch would result in the display showing "initialising" (or "starting", can't remember which now) and not proceeding any further in the boot phase. Would have to shut it down for several hours to completely cool then restart it for the sequence to happen all over again. Seems to be a rare occurrence. So it was off to the distributor for servicing. My beast is the last of the 1TB units, the 2TB beasts were already in the shops when I got mine. Had the latest firmware and software though.
So if your HDX is showing any of the same signs, I would have it looked at immediately by Naim.
Good luck, it is still an amazing piece of equipment even with this inconvenience.
...............the internet connection would then be dropped and hence control with an iPad would not work although you could still control it via the touch screen.
Yes, this happens occasionally. The fan is definitely working as it does kick in occasionally.
What was the resolution for you?

These temperatures are fine...

If you are having any issues then please contact either your dealer or me or Steve Hopkins at Naim directly ... there could be many possible issues that aren't necessarily related to the HDX itself and it would probably be sensible to try to identify what your specific issues are...
For example, if your HDX is not contactable from your iPad then is it still found by Desktop Client on a PC or n-Serve on a Mac?
Is the web interface to the unit still visible?
Can the unit be "pinged" on the network?
These are all fairly basic diagnosis steps that we can take a look at to identify any issues, there are also some fairly generic logs that are continually kept on the server products that we can look at and if we need to then much more detailed and targeted logging can be enabled as required.
So - please contact us directly - our contact details are in a sticky at the top of each forum.
Cheers

Thanks Phil. Unfortunately, I'm in the US so that's a little more difficult. I'll try the diagnostics you suggest when this happens again and post back.

Hi,
It shouldn't be any more difficult than anywhere else - our distributors in the US are quite capable and I often work around customers in different time zones so it should not be an issue to do diagnosis on your particular system.
Cheers

Temperatures of 49-52 degrees F....
Surely he meant Centigrade ?
Unless he listens to the stereo wearing an overcoat.....
I have complete trust in the Canadian Distributor of Naim products to be able to sort out the problems with my HDX. Based on past experience and service, they are very good, having recapped several of my other components over the years. Aside from the sound quality, it is precisely because of this level of service and the fact that I can, for the most part, have almost every piece of Naim gear in my collection serviced, updated and repaired when, and if necessary, that I started purchasing the gear many years ago.
In the case of my HDX, as the unit became hotter, the unit could not be "pinged", network connectivity was lost and as previously mentioned, the display froze. Expect that I will be getting my unit back in about another week to ten days from servicing.
I would expect that the US distributor should be just as efficient and thorough on the diagnostics and repair.

Nope, buck naked!
(yes, I meant centigrade - still haven't gone mertic here in the ol' US of A)
