I've cut my Firebox (to cool it down)
I've cut my Firebox (to cool it down) Posted on: 06.10.2010 by DJ MENSAH To prevent from hijacking unsuspecting threads, here it is:I don't like my gear to be running that hot and this summer was a bit too hot. So, few weeks ago I lightly modded Presonus Firebox sides to allow more natural airflow. Until now, it's been running pretty hot (for 1-2 years) and some users on the presonus community s have been complaining that their fireboxes might have fried themselves (but they were leaving them on all the time, even when computer was off). A small hand-dremel would probably be the best ( if you have a steady hand ) but I did not have access to any. I used a large cutting-dremel-tool (used for steel cutting, not hand-held hobby one) with the cutting stone marked 115 x 1,6 x 22,23mm ( Image ). I also tried thinner ( 1.0 mm ) wheel but it was wobbling too much. Also you can just drill many holes. I believe this method of mine ruined ( just a bit) the Faraday-cage protection that full-metal(-intact) enclosure has. I've cut in-between the "ribs", along the recessed lines, but not all the way, leaving top and bottom (horizontal) support beams intact. This way, side panels are still tough to serve it's purpose (and they are important part of the firebox case). There are no fans, it is that much cooler just by being allowed to exchange hot air naturally. Aside from that, I did not find a place where I'd tap into the power supply to insert fan (although I did not really try to hard). I believe you don't want fan inside it, since it might introduce noise into the circuitry. It is a minor mod but a lifesaver (hope it extends firebox's life). Sides got a bit scratched in the process but it is a small price to pay for a chilled-out soundcard. Story: The other day I was playing in a cramped booth and only place I could put the firebox was on top of a amplifier. When amp gets hot, firebox get extra warmth, not a pleasant thought. Anyway, with this mod, it was all nice and peachy. My cool-cat: | |

| DJ MENSAH 04.03.2013 | Thanks, it is still running. Sometimes for a few days in a row with minimal heat buildup. |
| Brunilda Kora 03.03.2013 | Awesome mod. Great work. |
| DJ MENSAH 31.10.2010 | Two more (better) pics. |
| Marguerite Salsedo 07.10.2010 | Nice write up of the mod, by clearing I meant the cutting between the "ribs" of the firebox. Not sure I have access to the necessary tools, though if I decide to try this I might be able to get access to my university's metalworking shop via some friends in engineering. Gonna have to look into that faraday cage protection stuff first. |
| DJ MENSAH 07.10.2010 | Just the 2 pairs of screws form the top and bottom, yes. Please: - make sure you thoroughly clean any metal leftovers after you are done - don't cut top & bottom rails as they are very important for the case structure - post pictures of the work after you are done (my pics are low quality) - make sure you don't spill drink on your firebox on your next party Like I said, drilling would probably be better for the sake of preservatiion of Faraday-cage RF protection. |
| robin loo 07.10.2010 | nice.. one might do this to my fb as well.. is it sufficient to remove the 4 srews on the top & bottom? |
| Leeanna Ayla 06.10.2010 | A drill bit would have worked just as well, but probably wouldn't have looked as cool. |
