My case is hot enough to cook a turkey

You give no particulars about the case cooling. If the case were minimally cooled then you running Prime may have created a lot of heat that was then stored in the air in the case, as well as all the other components. However, that wouldn't explain the temps the second time around. Also, you don't mention ambient temps. Was it 40°C cooler this morning? If that Coolermaster case didn't come with a rear exhaust fan (I vaguely recall reading some review where it might've had a fan in front of the HDD bay but not the rear exhaust fan), it would be good to either move the front fan to the rear (assuming it is the same, 120mm size) or buy a fan to place in the rear. If it has the two vertical mesh panels with the solid front as intake, and those mesh panels have foam filter inserts behind them, this foam will also significantly reduce airflow... even moreso after it begins to get clogged with dust. I like filtered cases but so many of them implement the filter poorly. |

Simply seal the drive bays from the rest of the system and vent the drive bay area on both sides. Add a fan to one side and there you go! |

The two drives currently installed, run at 31C and 32C respectively. (Room temp about 25C.) There are also holes in the rack, to allow airflow. That is why it all works. If I used the regular bays in the upper part of the computer, there are no intake vents up there, so the drive temp would be hotter in that case. Only an optical drive sits up there currently. Paul |

True, but look into case that have a removable front bezel, then you can pull them out the front instead of the rear. ...and, although case makers don't do this, it does give a straight path through the system to cool the drives without introducing the heat into the system. Simply seal the drive bays from the rest of the system and vent the drive bay area on both sides. Add a fan to one side and there you go! Unfortunately, fans mounted on external panels leak noise into the room. It is especially true with side panels because they are usually straight sheet metal instead of made more rigid with small flat areas before there are folds in the metal. If I had to choose between cool drives and quiet, cool would win every time but given a case where all the passive intake flows through the drive bay, you can have both w/o a front fan. |

wrote: I hear ya, but how do you know that the difference is significant? Common sense? On the one hand there are properly engineered HDD bays where 100% of the intake fan is through the HDD bay, and on the other hand, there are sideways bays where maybe 20% goes trough them. I'm not saying a sideways bay can't work, certainly it can, but when a fan is mounted on the front of a case it usually results in the most noise emission of any (otherwise low RPM/quiet) fans in the system. If a fan is meant for HDD rack cooling, the key to keeping good temps at low noise levels is maximizing efficiency. With a good case design, drawing all air intake through the HDD bay, a front fan isn't even needed. A resonable PSU and rear 120mm chassis fan can adequately cool a few HDD if the intake is all flowing through the bay. Unfortunately, too many cases are poorly designed such that all the intake is not through the HDD bay. They often have short-loop intake holes across from the motherboard slots, passive intake holes in the side panel, and low tolerance parts that result in intake between external bays and elsewhere. It is a shame they take the lazy way out but given some prep-work (and a case worth the work) these shortcommings can be overcome. I have an Antec P180 with the side-mounted SATA drives, and they both sit in a tunnel with air pumped from front intake to rear exhaust by a 120mm case fan and the 120mm PSU fan. I deduce that the HDs are actually running cooler than they would in a conventional case, but I've no way to to tell. It may depend on how you define conventional. Certainly there are worse cases. I always strive for *best* (within reason). Have you built essentially identical systems in the two different kinds of cases, so that you can actually make a direct comparison? I'd be very interested in the numbers. You may well be on to something here. It's not (temp) numbers, since there are several ways one can build what is cool enough, it's noise and dust buildup from any given design, and/or, maintenance interval since it is easy enough to just mount a half dozen low RPM fans on a case, but stray airflow does more to build up dust than hit problem cooling areas, unless everything is filtered but doing that again increases maintenance interval to change filtes, and fan noise to overcome the impedance to airflow from the filters. Getting maximal cooling depends on routing airflow across the parts that need cooling and minimizing stray airflow. Key areas that need more airflow (than the rest) include HDDs, video card, CPU, motherboard VRM subcircuit (especially if overclocking or marginal motherboard components) and PSU. PSU is a catch-22, you want good intake with minimal obstruction but still a 2nd case exhaust so the PSU is not drawing in all the heated air. |

There are also holes up by the fans where the word "Antec" is punched out of the side of the case. I'd think that would provide a short-cut for at least some air. If I used the regular bays in the upper part of the computer, there are no intake vents up there, so the drive temp would be hotter in that case. Only an optical drive sits up there currently. milleron you have a non-conventional case (I believe?) where the only area of entry for fresh air is directly in front of the bays. For the purposes of airflow patterns you essentially have two cases, one long thin one (think direct front-to-back airflow) for the HDDs/PSU and another for the rest sitting on top. As you say, a tunnel. Your experiences are only valid for others with that case type. I've built a few systems recently in conventional cases that have 120mm slow running fans directly in front of the HDD bay pushing air into the case. Some with traditional HDD bays and a couple with side entry bays. Just looking at them you should be able to predict the result. However, I've monitored them as well and see nearly 10°C higher temps on the side entry bays HDDs. The traditional bays let almost all the air pass through between or around the drives. The side-mounts rely on a small percentage of the air going through some smallish holes between the drives. However, when most of the air is actually bouncing off the steel sheet that the holes are in it tends to create a flow pattern that makes it even more unlikely that significant amounts of air will go through the holes. The air exiting the area to the side creates an area of low pressure behind it that *draws* more air after it. Air takes the path of least resistance and, unless the fan is jammed up against the holey panel with nowhere else for the air to go *but* the holes then it'll mostly go sideways. If it *is* jammed up against the panel then it's efficiency will be severely compromised. This is obviously more important where you have 'stacked' drives, as in a RAID array or several as JBOD. If you've got just one or two HDDs set well apart then convection/diffusion will help keep them cool. -- TTFN, Shaun. |
