Heat Sinks on 6000 Chips

[HDTVFanAtic]

I had the cover of my 6000s moving a R5000HD unit that had been installed in the former R5000HD Dish 6000 of Gary Murrel to a BEV 6000 IRD I had.

As I was moving the wiring harness between the 6000s, something seemed different besides the lack of the 8VSB module in the BEV unit.

It finally hit me. The Dish 6000 had 2 heat sinks on 2 chips about 1inch by 1inch square. The BEV did not. The boards seems identical except for the heat sinks on the 2 chips.

I purchased the BEV unit used about 1 - 1 1/2 years ago - so I don't know if the heat sinks were ever on the unit and the original owner did something to them - or maybe they were on early units but found not needed later on - or not on early on and found to be needed later

Should I be concerned that there are no heat sinks on the chips on one of the 6000 IRDs?

Heat Sinks

You could always attach an extra heat sink on the chip that does not have it with a tyrap or something, even heat sink grease may just hold the aluminum in place.

I searched on the internet for about 30 minutes trying to find some 1"x1" heat sinks with a large number of fins or whatever they are called coming from the top - in most cases they are not passive but with a fan.

I guess I am curious why one IRD has them and the other doesnt.

When I first saw your post, I thought the same thing. Try getting some heatsinks that fit.

How about these?:

www.digikey.com has heatsinks.

You could also try www.mouser.com.

I have seen 6000 receivers with and without the heatsinks. I'm guessing they added them onto later models. Possibly they had problems with overheating. I've owned a 6000 for many years without heatsinks and it seemed to work fine.


Edit: i searched through my catalog book and found:

5000 mod , cool... where is Gary?

 

[HokieEngineer]

Yea where is Gary? He fell of the face of the earth after the HD-lite bru-ha-ha.

 

[dfergie]

Not too apparent at Avs either Gary where ya be...?

He said he was going back to school and didn't have time for HD any longer 0 Had 500 DVHS tapes and figured that would last him for a life of watching

So I purchased his R5000HD mod and moved it into a BEV 6000.

Wow...should have asked here first instead of coming up with things that wouldn't work on the search engines! Thanks!
