I need to cool my system down - preferrably with AIR cooling. Not willing to invest in water cooling just yet.
I have a Zalman 7700 AlCu heatsink, and 2 120 MM fans. Look at the below pictures for details
The fan by the hard drives is an intake fan, sucks the air from the harddrives and feeds it to the back case fan, which pushes it out.
Will adding more fans help? What kind of fans? Where should they be placed? (I tried to take pictures of all angles so you can advise me better as to the location.)
I have that case--I know what you need to do and it won't cost you much but time. With the side panel off carefully measur from the top and back of the case to the dead center of the Zalman (Ihave that exact cooler btw) replace the side panel and using those measurements mark the exact center that you derived earlier on that panel (use a bit of tan masking tape and a fine point marker). Make a hole for a 120 mm fan from that center mark. make the 4 mounting holes (use a fan or fan grill for a template) and here's where there are some different options.
1) Mount a Nexxus SIlent 120 using a silcone gasket or O rings and be done with it--that wil not only provide plenty of cool air for the Zalman, but also pressurize the case and make number 2 an option to consider....
2) Perform Mod 1 and also cut a blowhole in the top--this will take careful placement--be sure to remove all your elctronic bits before cutting into the case--an 80 mm would be sufficient, but a 92 or even a 120 might be better--depending on the length of your optical drives/cables.
3) Preserve your hearing and mount a 92mm (like an Antec) and use a cheap PVC 3" to 4" Dryer Hose neckdown (about a buck) and carefully cut it with a sharp utility knife to fit over the sides of the fan body snugly--the 4" side against the fan/side panel; the 3" side about an inch from the center of the Zalman when the panel is closed. I have done this and it dropped my temps immediately--it is essentially force feeding the Zalman and nothing else.
Change out the Rear fan from Antec--or use it in the side panel and put a more potent fan on the exhaust.
From my experiments the center fan behind the hard drives did nothing to lower CPU temps (but it did help keep the SCSI drive cool
I've attached pictures of what I'm suggesting--it worked well for me.
The clear acrylic piece the antec mounts to is a 120 to 92 adapter I got from Coolguys--the 120 was too loud for me. I tried a 92 to 80 adapter I also have laying around and it was too restrictive--the home-mod dryer hose thingy out of PVC was better.
The case was a Lian Li--but I know the Sonata well (I'm looking at it) and the mod would work for that case fine.
