I use a P4C800-E Deluxe, and I later recently added an AT PS to the case so I wouldn't "tax" the Fortron too much since I will be adding more things in the future (larger monitor, 3rd & 4th HD's, etc). You can see details
here. I haven't added any text to the pages yet, but you should be able to figure it out by the thumbnail captions. Clicking "Figure 1" on the bottom left of page 3 will show the fan & sensor details and locations. Actually, it's 22 fans. The 23rd is the video card fan which is powered by the video card, although in the end it's still powered by the PS. (There's only 5 pages total now, so it stops at 5.html). Note one of my fans is 8000rpm+, and I have an 80mm that's 5700rpm (Tornado) and a 92mm that's 4200rpm of which all sound like a jet engine.
Temps are all
VERY cool. The highest temp I get is on the newly added AT supply which is about 83-88°F. All the others are in the 70's except for the HD's which are 79-80° for the Maxtor and 88-100° for the WD740. The sensor for the WD740 is on the bottom on its spindle. I don't have a temp reading on the Fortron, but its case is cool to the touch.
I've never used the Antec so I can't speak on it. But they it may have been part of the list tested at Tom's or Anand. I'll see if I can find the PS review links if you couldn't find them.
On a case for a customer where I use an IS7, I added a 120mm/4.7" fan on the left side door of the case. I took pix of the steps of it, but I "lost" the images since they are encrypted from another XP install! I just used a "Spiral cut roto tool" to cut out the hole, after of course getting the
EXACT dimensions of the fan's "blade diameter". Then I put a 120mm filter and grill on it.
I have detailed post somewhere on these message boards about fan sizes Vs. air pressure. I can't find it now. It's on the P4C800 thread, but I don't know which page. In short, a
SMALLER fan with
HIGH rpm is better than a larger fan with slower rpm because the smaller fan has a MUCH higher static air pressure. This is simple physics. It's the air pressure on a chip or heatsink that gives it the cooling, not the CFM. CFM is good for general case fans in the front and rear, but when cooling specific devices; that's where you want the high static air pressure. An example would be the HSF unit on my CPU. My HSF unit came with a 70mm fan. While trying to short its sensor so it would create more air pressure/higher RPM/more CFM, the sensor broke off. So, I tried a 70-80mm adapter and some 80mm hi-speed high CFM fans. Then I tried a 70-60mm adapter and tried the 8k rpm Delta 60mm fan I have on it now, and the 60mm fan has
MUCH cooler CPU temps. This is because the air coming from it is in more of a "concentrated" area. Even though it has lower CFM than the 80mm fans I tried, it has more air pressure and cooling potential since it's smaller with higher pressure and higher RPM.
You'll notice that yellow adapter on my HSF unit, and the CPU fan in a very unusual position with respect to that Thermaltake ducting mod. (I haven't added comments & details on it yet). Instead of having the fan where it is usually placed on the duct mod "elbow" (on the top), I have the fan in the usual place
on the HSF unit, then I placed the ducting mod
on top of the HSF fan unit. This was so the front case fans and rear case fans would not "suck air" away from the fan on top the the ducting mod, on top of the HSF unit, because the CPU fan would have been right "under" the path of high speed air flow. And as you know, higher speed air = lower air pressure. As it is now, the ducting mod
"scoops" air from the front case fans compared to in the conventional positions (fan on top of ducting mod) which created a low pressure area moving across the top of the HSF unit fan therefore starving the HSF unit fan for air. Also, again showing how air pressure works; that ducting mod that Thermaltake CLAIMS "will result it lower CPU temps" is bogus. When the fan was in the typical location on it, that
INCREASED my CPU temps due to the simple fact that it reduced air pressure on the heatsink (HS)!!! The way it is now, the fan is directly on the HS giving it more air pressure and lower temps. They even claim that their ducting mod reduces temps by eliminating the "dead spot" of zero or no air flow under a fan's hub by the mod placing the fan at an angle to the HS. Not true. Not using the ducting mod would have resulted in the same potential problem of low air pressure/high speed air passing
just over the top of the fan on the CPU starving it for air. So, I used the ducting mod as an air scoop.
