Overheating BPPC component

[Framiga]

and this is why P5 had done those custom heatsink ;-)

Anyway . . .you should:

reinstall the original fan-heatsink more an additional fan on top the "thing"

or like you said, to add a small heatsink on those controller.

Remember that even the 2 IC regulators, goes hot as well.

EDIT- if you have enough space (tower), you could use heatsink on PPC-040-controller-regulators and a BIG Low rpm-Low noise fan (ie 92mm) blowing air on the whole card.

if you want to purchase a thermal glue you can.

I personally use the normal thermal compound, with 4 little drops of cyanocrilate, at the 4 corners.

Apply the thermal grease on the chip, then clean the 4 corners, apply 4 "very, very little drops" of cyanicrilate at the 4 corners and push on the heatsink . . .  .QUICKLY ;-)

It works and you can easily remove it, if needed.

NOTE- pay only attention to use the right amount of thermal compound (to avoid that the thermal compound, goes onto the IC pins)

Hi AmigaMance

i think that we have (more or less and in different way) already answered to your question.

There aren't absolute bahaviours in such overheating situations. Usually CPU overheating, could freeze, crash even burn you CPU (but this is not your case, seen that you have already cooled it)

Then there are:

ICs regulators (2), the ram controller (those CY7C37)

The setup suggested by x56h34 its quite OK . . .but NOT remove the original 30x30 mm fan . . . .that is not there only to collect dust! ;-)

If you don't like the P5 solution, go for a separated heatsinks for the above mentioned components. (with a fan on PPC and on the 040)

At a side note, i've recently read an interesting article about hi quality and safe thermal glueing.

To avoid that the thermal adhesive, will broke the CPU if you need to remove it, its enough to mix the thermal glue with the thermal compound (in 1:1 rate).

You will need i'e Artic Silver adhesive and Artic Silver compound mixed at 50%.

Will be more easy to remove it (and Artic Silver is a very, very good product).

Last suggestion: check carefully that the heat of the components, is fully transfered to the heatsink (sometimes the haetsink "seems" cool only because, the thermal compound is applyed in a wrong way).

An easy way to check this is . . . run for about 30 seconds the system with the fan switched OFF.

The heatsink MUST rise the themperature rather quickly . . if not, there is something wrong on the heatsink installation.

If the heatsink will go warm quickly, you are OK . . . try it for no more than 1 minute or so and the shut down :-)
