Thanks for all the suggestions! smile

Yes, round hole also sounds a great idea (and I have plenty of rubber pins, actually). The only issue with the idea of attaching the fan to the side panel is that the side panel is completely removable and I'd have to disconnect the fan form the MoBo (or from the extension cable) every time I remove the side panel to open the case. Not a big annoyance, but still, I'd rather avoid that.
The foam weather seal is a great idea, I'll do that. I should have some already! smile


Now, some more interesting news: 9cm fan, full speed, side panel completely removed, and temperature does not decrease below 35 C / 37 C ! So, the SIZE of the fan seems to have a significant impact in this particular case.
