VU+ SOLO SE V2 Heating Problem

[Archive7]

I have the VU+ SOLO SE V2 Dual tuner DVB-S2 for several months now and it has a major problem with the heat, even on a cold day like today, I can feel it getting hot so I have a small USB fan near by to cool it down.
My sister needed a good satellite receiver and I ordered for her the VU+ SOLO Se V2 but with single tuner.
Does anyone know why this model gets too warm and if the tuner is the source of the heat (I can feel it is hot when I touch it near the LNB connectors), and whether it makes a difference operating a single tuner instead of dual tuner.
I know for sure she is not going to like the idea of using a fan all the time.
Thanks for any replies.

The difference in temperature from single to double is that, twice as much heat to dissipate.
In one you have a single voltage regulator and the heat is distributed throughout the body / chassis of the tuner and the F connectors that the module has.
In the dual tuner, you have 2 regulators that generate twice as much heat and now you have only half of material to dissipate the same heat that you generate.

With an ambient temperature of 24'5°C the dual tuner chassis has 47°C (sensor attached to the tuner plate inside the receiver) when the 2 tuners are in use (important).
If you touch the fingers of the tuner's connectors, they have 33ºC+/-, for your hand this is hot with your fingertips at 25ºC+/- (measured now with a laser thermometer).
In general, the electronics have no problems below 50°C.
Personally I try to keep this temperature lower with extra fans.
Under the temperature of the tuner connector at 33 ° C to 30 ° C.
The internal chassis is at 43 ° C at this time.

Measurements made on the VU + DUO2 that has the same tuner as the Vu + Solo2 SE V2 (Twin tuner).
----------
La diferencia de temperatura del simple al doble es esa, el doble de calor a disipar.
En uno tienes un solo regulador de tension y el calor se reparte en todo el cuerpo/chasis del sintonizador y los conectores F que tiene el modulo.
En el sintonizador doble, tienes 2 reguladores que generan el doble de calor y ahora tienes solo la mitad de material para disipar el mismo calor, que generas.

Con una temperatura ambiente de 24'5ºC el chasis del sintonizador doble tiene 47ºC (sensor pegado a la chapa del sintonizador por dentro del receptor) cuando esta en uso los 2 sintonizadores (importante).
Si tocas con la punta de los dedos los conectores del sintonizador, tienen 33ºC +/-, para tú mano esto es caliente al estar la punta de los dedos a 25ºC +/- (medido ahora con un termometro laser).
En general, la electronica no tiene problemas por debajo de 50ºC.
Personalmente intento mantener siempre mas baja esta temperatura con ventiladores extra.
Bajo la temperatura del conector del sintonizador a 33ºC hasta 30ºC.
El chasis interno esta a 43ºC en estos momentos.

Medidas realizadas en el VU+DUO2 que tiene el mismo sintonizador que el Vu+Solo2 SE V2 (sintonizador doble).

Diferencia viejo/nuevo sintonizador doble/Difference Old/New Dual Tuner.
Nueva foto donde mido las temperaturas/New photo where I measure the temperatures.
Los cables y conectores tambien disipan calor/Cables and connectors also dissipate heat.

PD:Sorry translations.

Thanks Tururu for your reply
Do you know the temperatures for the single tuner or you don't have this receiver?
Anyway, I suppose I can expect the single tuner receiver to be slightly cooler than the dual. The big question is by how much.

I use these for keeping my receivers cool

Thanks. I already use small USB fan which is very quite to cools my receiver.
I have spare one for my sister's receiver in case the single tuner is also too hot.

El doble es el usado en el deco que tienes VU+Solo SE V2, confirmado 100%.
El sintonizador sencillo, no lo puedo confirmar 100%, como lo tengo, estas son sus temperaturas.
-----------------------
The double is the one used in the deco that you have VU + Solo SE V2, 100% confirmed.
The simple tuner, I can not confirm 100%, as I have, these are their temperatures.

Ahora pongo unas fotos del sintonizador sencillo para que lo veas y compares/Now I put some photos of the simple tuner so you can see it and compare it.

Can I just say surely the heat is within "normal" operation parameters? Its almost like we're saying here "better get yourself a cooling matt or it might well fail within 18 months or sooner...." its like the dreambox 800 again.

Heat is the number one enemy of any electric device.
In the case of the VU+ SOLO SE V2, it's operating temperature will depend on which country the receiver is working. In Israel the climate is normally hotter than most countries in Europe and if the room temperature is 30C during the summer then you don't really want your receiver to sweat too much as it can become a fire hazard.
Today it is cool around 16C and there is no point in cooling it with a fan.
I like to run my devices as cool as possible as I believe this can prolong their life expectancy far longer than the warranty period.

Well that's very true, you get people who "stack" their av stuff onto of each other, just with two units you can absolutely cook the top box of the two, not good!!

Reminds me of my neighbor who is over 70 and one day she asked me to look at her TV why it is not working.
Well the problem was simple she pressed the wrong button and she didn't know how to select the correct AV again. But then I noticed that her router had all it's vents covered by all kind of things and it was really hot and the table was covered with black nasty stuff which turned out to be the black feet have melted from the heat. She blamed the cleaner of course.

This is one of the best for cooling a laptop or satellite receiver

Thanks. Is it possible to switch off the blue light or does it come without any lighting

The blue light is not visible from the front of the receiver just a faint blue light from the bulb on the reverse of the fan.

That's just asking for a fire that is! [emoji46]

Lo ideal es tener menos de 50ºC dentro del receptor, como digo, todo depende de la calidad de los componentes, 47ºC, <50ºC es una temperatura "normal".
<.-Menos ó igual a, como maximo.

Ahora los peros, con 24-25º de ambiente claro, si vives en paises "calidos", es lo que tiene Israel/España, no veas el frio que hace en verano.
En España, en verano, 34ºC es lo normal y hasta 38ºC de ambiente en verano (10-30 dias sobre las 16:00), recomendando mover el aire para refrigerar mejor receptor.

En equipos con componentes de mala calidades y mal diseñados para su refrigeracion, tiene un problema con esta temperatura, es mi caso en verano.
La recomendacion es refrigerar el equipo, con aire forzado de algun ventilador, arriba, abajo, dentro.
El VU+DUO2 tiene 1 ventilador de origen + 4 extras (tuner, CPU, Hdd, power supply), no veas como se notan los 5ºC mas frio que esta comparado con su hermano gemelo sin los ventiladores, para comparar.

In equipment with poor quality components and badly designed for cooling, has a problem with this temperature, it is my case in summer.
The recommendation is to cool the equipment, with forced air from some fan, up, down, inside.
The VU + DUO2 has a fan of origin + 4 extras (tuner, CPU, Hdd, power supply), do not see how you notice the coldest 5ºC compared to your twin brother without the fans, to compare.

Would one of the heat-pipe devices used in some specialist high performance PCs be a possible solution to keeping the tuner modules cool?

I use this USB fan and it does wonders to cool my receiver very cheap and very quite

This is mine as you can see no blue light showing at the front end.

OK Good.
Unfortunately they don't ship to Israel

The VU+ SOLO SE V2 has an eSATA port and two USB connectors.
I want to free one of the USB connectors and use an eSATA HDD instead for recording.
It is hard to find an eSATA HDD these days but I found a case that comes with eSATA cable and power supply all I need is to insert a SATA internal HDD.
Has anybody used an eSATA and would I expect any problems using it?
