Greetings fellow Air-heads (and water-dudes too - Oh! and Pelties, Freezers Phazers and whatever else there is)...<br><br>
I really like my P180, but I have a couple of issues with it. The first is the lack of wire management possibilites <img alt="" class="inlineimg" src="/images/smilies/mad.gif" style="border:0px solid;" title="Mad"> , the second is the lack of a stock filter on the airbox intake <img alt="" class="inlineimg" src="/images/smilies/mad.gif" style="border:0px solid;" title="Mad"> (That's my next small mod), and the "Heat-hole" that forms between the PSU chamber wall, the bottom of the airbox and the VGA card:<br><br>
I wanted to turn this: <a href="http://img90.imageshack.us/my.php?image=airflowdiagramhotrf8.jpg" target="_blank"><img alt="" src="http://img90.imageshack.us/img90/6519/airflowdiagramhotrf8.th.jpg" style="border:0px solid;"></a> Into this: <a href="http://img170.imageshack.us/my.php?image=airflowdiagramcoolot2.jpg" target="_blank"><img alt="" src="http://img170.imageshack.us/img170/4817/airflowdiagramcoolot2.th.jpg" style="border:0px solid;"></a> The blue circle represents the 80mm Panalfo that blows down on both sides of the VGA card.<br><br>
I started with a piece of plastic that was a cover to a grout sample case. I purposely looked for a piece that a 90 degree angle to match the rear panel covers, and was of the same gauge. For the fans I dismantled a HDD cooler that I was duped into buying. What a POS ! For it to drop the temp on the HDD 1C it had to be on full-blast. I swear it sounded like an unholy choir of tone-deaf Harpies! Since I only wanted a very low exhaust I felt that these would do. To make sure I hooked them up to a test bench PSU and fan controller - they were good enough.<br><a href="http://img89.imageshack.us/my.php?image=traysw4.jpg" target="_blank"><img alt="" src="http://img89.imageshack.us/img89/2729/traysw4.th.jpg" style="border:0px solid;"></a> <a href="http://img89.imageshack.us/my.php?image=fansru6.jpg" target="_blank"><img alt="" src="http://img89.imageshack.us/img89/8534/fansru6.th.jpg" style="border:0px solid;"></a><br><br>
I took rough measurements of the required width and height and made my basic cuts. As luck would have it, one of the rolls of electrical tape was almost the perfect diameter for a template.<br><a href="http://img170.imageshack.us/my.php?image=measurewithbracketpk1.jpg" target="_blank"><img alt="" src="http://img170.imageshack.us/img170/3946/measurewithbracketpk1.th.jpg" style="border:0px solid;"></a> <a href="http://img146.imageshack.us/my.php?image=measurewithbracket2bj9.jpg" target="_blank"><img alt="" src="http://img146.imageshack.us/img146/1120/measurewithbracket2bj9.th.jpg" style="border:0px solid;"></a> <a href="http://img146.imageshack.us/my.php?image=cutscompletedwx0.jpg" target="_blank"><img alt="" src="http://img146.imageshack.us/img146/28/cutscompletedwx0.th.jpg" style="border:0px solid;"></a> <a href="http://img301.imageshack.us/my.php?image=gaugingroundholes2kd2.jpg" target="_blank"><img alt="" src="http://img301.imageshack.us/img301/7633/gaugingroundholes2kd2.th.jpg" style="border:0px solid;"></a> <a href="http://img301.imageshack.us/my.php?image=holesdrawnpc9.jpg" target="_blank"><img alt="" src="http://img301.imageshack.us/img301/5193/holesdrawnpc9.th.jpg" style="border:0px solid;"></a><br><br>
I used a Dremel and 2 different attachments. I started by scoring on the inside of the circle that I had marked. Once I had a guide, I slowly cut the circle out. I finished the cut and cleaned the edge using the drum sander attachment. Then I placed the fans over the holes and marked the screw holes, then drilled them.<br><a href="http://img137.imageshack.us/my.php?image=cuttingwheeleb4.jpg" target="_blank"><img alt="" src="http://img137.imageshack.us/img137/8729/cuttingwheeleb4.th.jpg" style="border:0px solid;"></a> <a href="http://img96.imageshack.us/my.php?image=drumsanderav1.jpg" target="_blank"><img alt="" src="http://img96.imageshack.us/img96/4564/drumsanderav1.th.jpg" style="border:0px solid;"></a> <a href="http://img137.imageshack.us/my.php?image=initialroundscoringce2.jpg" target="_blank"><img alt="" src="http://img137.imageshack.us/img137/5535/initialroundscoringce2.th.jpg" style="border:0px solid;"></a> <a href="http://img96.imageshack.us/my.php?image=roundholescutmh0.jpg" target="_blank"><img alt="" src="http://img96.imageshack.us/img96/4383/roundholescutmh0.th.jpg" style="border:0px solid;"></a> <a href="http://img137.imageshack.us/my.php?image=roundholescut2hi4.jpg" target="_blank"><img alt="" src="http://img137.imageshack.us/img137/3389/roundholescut2hi4.th.jpg" style="border:0px solid;"></a> <a href="http://img175.imageshack.us/my.php?image=roundholescut3vu2.jpg" target="_blank"><img alt="" src="http://img175.imageshack.us/img175/8937/roundholescut3vu2.th.jpg" style="border:0px solid;"></a> <a href="http://img96.imageshack.us/my.php?image=markmountingscrewholesim5.jpg" target="_blank"><img alt="" src="http://img96.imageshack.us/img96/2663/markmountingscrewholesim5.th.jpg" style="border:0px solid;"></a><br><br>
After mounting the fans, I re-sleeved the cable and did my final cuts and adjustments so that the fans would fit snugly and be relatively air tight (all surfaces were flush and no part of the Mod contacted the MoBo). I cleaned up all the edges with an emery board and gave the unit a thorough blowing with some canned-air. Here is the completed unit:<br><a href="http://img155.imageshack.us/my.php?image=completedfansfv5.jpg" target="_blank"><img alt="" src="http://img155.imageshack.us/img155/5584/completedfansfv5.th.jpg" style="border:0px solid;"></a><br><br>
I debated as to whether I should cut the brackets out of the case, but quickly vetoed the idea. Since this was intended to be a low-pressure exhaust, I reasoned that the brackets could remain in place. I also decided to use high-temp double-sided tape on the mounting tab instead of screwing holes and using hardware. I justified my laziness to myself by saying, “Self, using tape will make a nice gasket!†The final picture in this sequence shows the mounting sleeve for the airbox. This gives an idea of the “hot-zone†created prior to the mod.<br><a href="http://img224.imageshack.us/my.php?image=fansmountedoustsidehr4.jpg" target="_blank"><img alt="" src="http://img224.imageshack.us/img224/1002/fansmountedoustsidehr4.th.jpg" style="border:0px solid;"></a> <a href="http://img157.imageshack.us/my.php?image=fansmountedinsidews6.jpg" target="_blank"><img alt="" src="http://img157.imageshack.us/img157/391/fansmountedinsidews6.th.jpg" style="border:0px solid;"></a> <a href="http://img228.imageshack.us/my.php?image=fansmountedinside2uz0.jpg" target="_blank"><img alt="" src="http://img228.imageshack.us/img228/3955/fansmountedinside2uz0.th.jpg" style="border:0px solid;"></a> <a href="http://img224.imageshack.us/my.php?image=mountedwithairboxsleeveoz2.jpg" target="_blank"><img alt="" src="http://img224.imageshack.us/img224/3972/mountedwithairboxsleeveoz2.th.jpg" style="border:0px solid;"></a> The newly installed exhaust is contolled by a Vantec Nexus.<br><br>
This point of this picture is to give an idea of the void that lies behind the airbox: <a href="http://img224.imageshack.us/my.php?image=theholeti1.jpg" target="_blank"><img alt="" src="http://img224.imageshack.us/img224/4216/theholeti1.th.jpg" style="border:0px solid;"></a><br><br>
Here is my system re-assembled. I also took advantage of the opportunity to relocate my HDD to the lower chamber. This gave a straight-thru shot for the cold air intake (Silverstone FM121). The HDD is still getting airflow as there is a “deep-pitch†120mm in the lower chamber.<br><a href="http://img92.imageshack.us/my.php?image=fullycompletednm6.jpg" target="_blank"><img alt="" src="http://img92.imageshack.us/img92/8493/fullycompletednm6.th.jpg" style="border:0px solid;"></a><br><br>
The entire process took about 3 hours time and was done with materials that I had on-hand.<br><br>
Was it worth it? The temps in the questioned region have dropped 3C and the volt-modded 7900GT is about 2C cooler (only under VGA load – idle is the same as before). Meh!<br><br>
It was a great little experiment (though not original), and for now I will leave it in place. Fortunately for us winter is on the way (summer kills as I have no AC and I live in California). Next summer…Water baby!<br><br>
I hope that you enjoyed this little sojourn as much as I did.<br><br>
Coming soon: Open test bench and later on down the road and acrylic custom case.

hmm nice simple mod. Quick question, does the modding contest require it be a case that is for sale? Because I want to fabricate my own.
