5.25 drive bay 120mm fan mod

thingiverse

For us few who prefer a mid atx over a full sized case we often have to sacrifice front cooling options for overall case size. I came up with this design so I could once again add an additional 120mm front intake fan to my partner's precision 1500 case, notorious for having zero air intake fans. It's running an i7, 16gb of ram and a 580gtx, so as you can imagine it can get pretty toasty pretty quick in there... especially when she's obsessively building a new ride on planet coaster [rolls eyes]. I did offer to simply re-case the pc into a more airflow/water cooling capable case but she stubbornly refused [rolls eyes the other way]. Anyway... This is a 3 part design, very simplistic in nature but effective in execution (if I do say so myself). It uses the two 5.25 bays typically only available in a mid-atx case and positions the 120mm fan at an angle suitable to fit but still flow air cleanly. Results were evident when I measured ambient internal temps before and after, there was a 16°c temp drop with the new fan mod which is pretty good considering the fan I used wasn't the fastest in the world (she said she wanted a purple fan which kinda limited my options [places head in hands and sighs deeply]). In case it missed anyone's attention, yes in a two bay case it means sacrificing the dvd drive but ffs who uses disks anymore anyway???, plus it's a small loss for the much improved airflow in my opinion. Print Settings Printer: poltur XL Rafts: No Supports: No Resolution: 0.3 Infill: 20% Notes: Forgot to mention... Yes, it's usable in any ATX case with 2 or more drive bays. No, it doesn't need to be fixed permanently together, the fitment of the three parts are pretty darn snug around the fan so there shouldn't be any vibration issues and once it's slotted in place it can't separate. Yes, the angle of the output is downward so the cool air coming in goes somewhere useful and not just shot straight at the exhaust fans at the back of the case Addition 26/2/2017: Added revised design for use with 25mm thick fans, original version is for 20mm slim fans Additional 03/04/2019: Added the STL's for a Hex facia version that I just added to my own rig
