They're fond of putting heat intolerant components, such as electrolytic caps, right next to heat generating components. I have a Philips television camera with electro caps actually strapped onto a heatsink (not to cool the caps, the heatsink's for something else). Side of the chassis mounted large fans that blow over whole cards are a good idea, cooling the *whole* card, rather than just having small fans on some heatsinks for some devices on the card, can be very useful, especially in hot environments. That made a big difference to one graphics card I had, it's fan barely made a difference to the thing it was mounted on, and it eventually melted and seized up. Meanwhile other parts on that board were burn-your-fingers roasting hot. But with one fan doing the whole card, the whole thing stayed cool. I haven't gone as far as doing smoke trail tests, but I've waggled my finger tips around inside, to feel where the air does and doesn't go, and made a cardboard reflector to change the flow of air onto something that really needed it on one PC. The average home PC is a bad design, often sucking air in from the floor, pre-loaded with dust and carpet fluff. Just getting tower PCs off the floor can make a difference. Heatsinks do not work when clogged up with fluff, and it gums up the mechanics of fans. -- tim@localhost ~]$ uname -rsvp Linux 3.19.3-100.fc20.i686 #1 SMP Fri Mar 27 17:30:08 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
