I was trying to quiet down my stock p4 3.0 in a full tower chieftec monster case, so I did the following:
- Replaced stock 80mm chieftec fans with 80mm pc power&cooling silencers (2 front intakes, 1 side intake, 1 rear exhaust). The silencers should be 20dB, 27cpm, but seems like everybody is skeptical about 27 cpm.
- Removed the stamped out grills in the front and in the back. Put some spun fiberglass AC filters on the intakes.
- Replaced the stock HS with Zalman 7000 AlCu, no lapping, just cleaned with isopropyl alcohol and used the thermal goop that came with the Zalman.
Well, things did quiet down, but MBM5 was reporting 35C cpu / 32C case idle, 51C cpu / 37C case under full load. I figured the silencers were sucking more (or rather, less) than they should have been, and removed the side panel. The temp drop was pretty negligible: 33 cpu/31 case idle, 51 cpu /36 case under load.
So now my question is... What did I do wrong? I'll get some AS5 and will reinstall the HS, but this won't drop the case temps. I could put in another 80mm exhaust fan in the back, but I don't want negative air pressure in the case. The airflow in the case should be ok, all the cables are tied down along the walls.
Anything else I'm missing?
My system is a stock p4 3.0 (no desire to overclock, just want cool and quiet), intel 875PBZ mobo, radeon 9800pro with stock cooling (will deal with when this is resolved), chieftec 420Wt PSU with 80mm intake fan on the bottom, 80mm exhaust fan on the back (both are pretty quiet).
Any suggestions about cooling AND further silencing without major case mods (need to be able to revert to native state for warranty purposes) will be much appreciated.
