That is a strange thing for someone to write, front case fan is in front of HDD rack, maybe he meant he had to do away with the front case fan to mount the hard drive further towards the front of the case? From the pic, it looks like the fan actually does mount between the HD rack and the MB. I can see the 4 screw holes for the fan. http://www.newegg.com/Product/ShowIm...Power%20Supply "Cons: Just a wee bit too short to put in an HD 4850 and a 120mm mid-case fan. The card fits, but the power plug sticks out of the front too far and butts up against the fan. Hopefully cooling will be okay without the fan in there." http://www.newegg.com/Product/Produc...ords=(keywords) Ok, but I still think what is closer to your needs is a deep case rather than a taller (than midtower) one. In the typical full tower you have the upper rack and the PSU right above the motherboard still so there isn't actually any more clearance available, just more rack slots and an empty area above the PSU where some accomodate a redundant 2nd PSU, some allow putting in a fan there (unnecessary to have a fan there). With a traditional hard drive rack where the data cables plug into the rearward facing edge of the drive, a case deep enough to give you some wiggle room with a full length video card and drives in the rack would be about 19" deep, a little more if the front case bezel is a fancy shape that bulges out for some reason. That depth includes space in front of the drive rack for a typical 1" thick fan, but it is only an average, case manufacturers can do strange designs sometimes and if the drive rack is rotated 90' so the drive plugs face the side panel instead of the back you can go with an inch or two shorter case but two is pushing it. Actaully, I was eyeballin this one last night. http://www.newegg.com/Product/Produc...82E16811517004 Cooling System 120mm Fans 1 x 120mm fan in rear 140mm Fans 2 x 140mm blue LED silent fan (19DBA) in front 230mm Fans 1 x 230mm blue LED silent fan (24DBA) on top 1 x 230mm blue LED silent fan (24DBA) on the side lol |

For this case, and the Antec Three Hundred, though, I can say they are roomy. I have not installed the front fan, but there would still be room enough to pull the motherboard if need be. |

I'll have to think about it. Take a look at Rosewill cases. http://www.newegg.com/Product/Produc...E&N=2010090007 +50002177&QksAutoSuggestion=&ShowDeactivatedMark=F alse&Configurator=&Subcategory=7&description=&Ntk= &CFG=&SpeTabStoreType=&srchInDesc= I bought one to house my current system I built two years ago. Some models come with a 120mm fan and room for a couple more with dust filters. Some models even have a duct to vent the CPU heat directly to the outside. Very nice. The duct isn't all that useful. The typical intel retail heatsinks blow down instead of up and most of the best heatsinks are now a heatpipe design that blows up or rearward. Whether it's useful or not depends on your system. With yours, no; but with mine, an Athlon 64 X2 one, there is only a heatsink and fan (came with the CPU), and it sucks air through the sink and exhausts the heat out the top of the fan directly into the duct and to the outside. If you hold your hand over the vent, you can feel the warm air. There is also a low, side-mounted 120mm fan with an dust filter (I clean it frequently.) that sucks in cool outside air and maintains slight positive pressure inside the case with air exiting through front and rear vents as well as the CPU ventilation duct. A PSU with a single 120mm fan efficiently exhausts air from the "dead space" above the drive bays. If I really needed to, there are two other places to mount case fans. All in all, a fairly well designed case, I think, and very quiet. I generally just take the ducts off and put a piece of plastic or cardboard over the hole as it countermines good airflow by causing a short loop where the exhaust fans just pull in air through there only to exhaust it after a small # of inches travel without cooling anything... better to have more of the exhausted air pulled in through the front cooling the HDD rack, southbridge. On the other hand I wish more cases had a fan hole lower across from the video card AGP/PCIe slot, then you can put an intake fan there and in front of the HDD rack and have the best of both worlds. My case has that feature. That's where I remounted the 120mm fan that came with the case. The fan was originally installed on the rear panel. It blows directly on accessory cards, and, of course, the graphics card. The air also blows on the motherboard itself and its heat pipe assembly. Stef |

Is the duct direclty coupled to the heatsink fan? If not, it isn't making much difference but in the majority of cases and motherboards they aren't directly lined up both on the plane parallel to the motherboard and due to distance between the fan and side wall of the case. Sometimes the ducts are extendable to reach, but ultimately there is one main thing that caused the duct trend, that Intel had an excessively hot (for it's performance) P4 Prescott CPU that it refused to ship with quality heatsinks using all copper base and heatpipes. Intel then tried to shift the industry to BTX, but some thought the side duct was a concession instead of moving because yet another fan hole seems a "feature". If you hold your hand over the vent, you can feel the warm air. There is also a low, side-mounted 120mm fan with an dust filter (I clean it frequently.) that sucks in cool outside air and maintains slight positive pressure inside the case with air exiting through front and rear vents as well as the CPU ventilation duct. In that case, you could say the same about cutting a hole anywhere. So long as you maintain the positive pressure I agree it reduces the negative impact of a duct and it may even slightly help, but it is one of the least important features in case ventilation and all the factors have to be just right to see any benefit, which with the typical case they usually aren't. A PSU with a single 120mm fan efficiently exhausts air from the "dead space" above the drive bays. If I really needed to, there are two other places to mount case fans. All in all, a fairly well designed case, I think, and very quiet. ?? What case are you talking about? PSU exhausts out the back and draws from any higher pressure area. Is is best to avoid drawing air from dead space, rather keeping airflow across hot parts. I generally just take the ducts off and put a piece of plastic or cardboard over the hole as it countermines good airflow by causing a short loop where the exhaust fans just pull in air through there only to exhaust it after a small # of inches travel without cooling anything... better to have more of the exhausted air pulled in through the front cooling the HDD rack, southbridge.

Stef You took the rear panel fan and moved it, but didn't put a fan on the rear to replace it? If that is correct the case is not cooling optimally unless you have the rear end butted up against a wall or furniture so it blocks the fan hole in the rear. |

PSU exhausts out the back and draws from any higher pressure area. Is is best to avoid drawing air from dead space, rather keeping airflow across hot parts. It's a Rosewill case. Don't recall the model number. Probably been discontinued, anyway. Got it from Newegg. The PSU exhaust out the back, too, but where traditionally one would find a 75 or 80mm fan, there is only a vent. The PSU cooling fan is on the bottom, a 120mm one, at least. It pulls air from inside the case and blows it out the rear vent. Different arrangement, but effective; and QUIET! That's one of the reasons I got that particular PSU. The system is in my bedroom, and runs 24/7. The last system I had roared like a freight train trying to make up lost time. I had no intentions of living with another system that noisy. On the other hand I wish more cases had a fan hole lower across from the video card AGP/PCIe slot, then you can put an intake fan there and in front of the HDD rack and have the best of both worlds.

If that is correct the case is not cooling optimally unless you have the rear end butted up against a wall or furniture so it blocks the fan hole in the rear. The case has several places to mount fans that also double as vents, if there is no fan there. That is, no gaping holes. The fan that came with the case, a 120mm one, was mounted initially on the rear, and setup to suck air out the back, but I wanted to BLOW cool, outside air directly on the accessory cards, graphics card, and heatpipe. There was a filtered vent on the side panel with fan mounting holes that was in exactly the correct position to do that. So, I moved the fan. I had intended to put another fan at the front of the case--there's a mount for one--to pull in outside air, blow it across the hard drives, etc., but I found that the PSU fan, a low speed, high volume one, provided enough additional air flow that I didn't need to do that. Serendipity strikes, again. I monitor the temps, and even when it gets up to 90F in the room, everything is still in the stated safe ranges. Stef |
