Overheating Gamma cards

[errolgib53]

I found by putting a PC fan with a 9v power supply it stops the overheating. Cheers.

Yes it does, but does it make a continuous annoying whining sound ???

I found that 5V is perfect, with no annoying sound.

Oh is that what it is?
I always thought that was the missus

Wont putting a fan in their end blowing dust everywhere and potentially cause problems?

The best way to prevent the heat is with the b_franklin mod , if this is still not cool enough for you place a heat sink on the top with a contact to the card . a fan is only cooling the plastic , where as the heat sink is pulling the heat away from the chip .

The fan must be doing something, because the one I have seen does not even have the slightest brown spot on the card.
Card looks new.

If there is a way of using an external phoenix (a JayCar MKII) - it hardly makes the card warm ...

Your not trying to cool the plastic your trying to cool the chip , could have a white card with no burn mark stop, your only stopping the heat from escaping the area and cooling the plastic at the same time (which is why no brown mark) . the chip is still gettting hot !! . A heat sink is the better way and no fan needed . . .


But all to his own . if it works for you then great and its always good to see people sharing knoledge .

Thanks gw1 between your first post and second I have come up with a working solution.

After trying your second mod the the TDA8004 shut down ( too much current draw?) . I was at a loss with what to do and then re read your earlier post where you express concern for overloading the TDA.

I have taken the 5v straight from the 5v input to the board (pin 2) and I am only using the 47uf tant on the output of the voltage regulator without the 180R resistor or the .47uf cap on the input of the voltage regulator and I get 3.3v at the card and it works fine.

The card runs very cool significantly cooler than in a cam about the same temp as my card in a programmer.

Thanks again

Hi Guys,

I have been informed by an Mate that this mod is the easiest for Humax's: just gently desolder the third leg on the chip and then earth it and hey presto 3 Volts and the card runs cool. Has been running it for a week and no probs.

Where is the earth?

Here are some pics of the slightly modded gw1 humax mod.

Just solder a wire to anything on chassis that can be earthed. This part not necessary just added safety measure.

I see that you can now buy external card readers for Strong receivers to avoid the heating problem...

See the other thread regarding the 'factory' mod.

Card now very cool..

G'Day Cobbers,
Just to let EVERYONE know where this thread has gone.
Very naughty of you to keep it secret.

as i stated earlier, it may have something to do with the version of o/s on the card.....

newer whiteys seem to run cooler from what i can gather...........

i use the open box x810 it dosn't burn the card, overall its a good box and cheap around $100
