In essence, the main chamber of the Mini P has about double the vent area, both in and out, for much expanded airflow, despite having a smaller internal volume. All the HDDs now go in the upper chamber. The optical drive bays in the lower chamber are afforded only peripheral airflow from the PSU fan drawing air in through the bottom vent in the middle; there is no place for a fan in the lower chamber.
The big mm fan will surely dominate airflow patterns in the case; like Rome, all roads lead to it. The SLM was positioned 35cm above and one meter from the top front edge of the case. This was the same setup used for acoustic measurements and recordings after a test system was installed in the case. Not an ideal acoustic test setup, but it had to do.
The mm fan is clearly quieter than the mm fan at any setting other than low. The actual sound character of the larger fan is more pleasant, as it consists mostly of wind noise whooosh and a bit of low level clacking or chatter at the low speed. Most of its noise is low in frequency, which makes it less audible, in general. Note : It sounds much worse in the recording than live, especially if you set the playback volume too high.
The mm fan sounds reasonably pleasant at the low setting but at the mid and high speeds, it is much louder, with unpleasant high frequency overtones. Despite the closeness of the SPL readings, the 23 dBA 1m of the mm fan alone on low is subjectively more pleasant than the 22dBA of the mm fan or the 24 dBA of both fans on low.
For the record, the big fan was removed and examined closely. Its basic design is sound, with struts probably no bigger than they have to be, and positioned correctly to be more or less perpendicular to the trailing edges of the blades to minimize tonal and turbulence effects.
We have no way of measuring the airflow as our fan test rig is set up for maximum mm diameter fans. It measures The hub motor, really measures 6.
Usually we try to push the thermal envelope, using components considered too hot by most silencers. Of course, these days, lots of enthusiasts want both quiet and bleeding edge performance. The heatsink testbed was installed into the for this review. The point was to find out whether the airflow created by the fans in the Mini P would be enough to cool everything without additional fans. More on that later. Overall assembly went smoothly. With good planning, it should be possible for an experienced builder to put a system together in this case in about an hour, perhaps less.
All the exposed metal edges are rolled in order to reduce the risk of cuts and scrapes during assembly. What follows is a photojournal of various points in assembly. Near the start, after installation of PSU. Note Ninja-installed motherboard on left. After the motherboard was installed, getting the AUX12V plug into the connector on the motherboard where the red arrow points proved to be nearly impossible with the Ninja in place.
Removing the big fan made it possible. The HDD was mounted in the top bay. Note that the grommets fit thicker on one side than the other; the HDD should rest on the thicker portion. The shortest optical drive on hand, just under 7" long, did not fit in the top slot. The big fan limits the top bay to devices not longer than about 6. An optical drive was unnecessary for testing anyway. In response to feedback from some readers, a double-check was made of the optical drive depth needed to use the top bay.
I found this LG, which fits. It measures mm, just under 6. There are others of the same size from other brands; in other words, an optical drive this size is not that difficult to find. The back end of the drive touches the big fan, but the cable connections clear the fan. Some tests were run with the integrated video at this point, to establish some baselines. This is enough space to accommodate any VGA card we know of.
After the ATI card was installed, tests were run with just the two stock case fans. Later, a Scythe Slipstream x25mm RPM fan was added as an intake as shown here, and further testing was done. Note: Either front vent can accommodate a mm fan, but not with the HDD bay in place.
Also, since the sliding door between upper and lower chambers was not used to route any cables, there was a bit of air gap. It was closed up with black electrical tape. The total AC power draw is about 5W lower than running it in default mode, but the stress on the GPU is higher, which means it gets hotter.
Heatsinks for the latter are still in a higher state of development than for GPUs. This stress load was bound to be easily handled by just the big fan alone, set to low. The mm fan was left unplugged. In this "negative pressure" configuration meaning air is forced to be sucked into the case via free vents as opposed to blown out , the only exhaust is through the mm fan, and all other holes in the top chamber become intake vents.
The mm fan, for example, becomes an intake, as do all the other vents on the back panel. Never mind that this Scythe Ninja Plus Rev. Note that the hard drive temperature remained constant at a very low temperature regardless of CPU load. It was utterly inaudible, swamped by the noise of the big fan. From time to time it will be necessary to wash the installed air filters. Not washing the air filters will result in higher system temperatures and possible stability problems.
We recommend checking the air filter at least once a month initially. The frequency will change depending on environmental conditions and system usage, as users whose. Push one of the fan grilles at the right middle edge to open the grille. There are two tabs on the filter. To remove the filter, use both hands to gently push the tabs downward. Slightly angle the top of the filter towards you before lifting it up and out. Saisissez le panneau en haut et en bas et glissez-le vers vous pour le retirer.

We take a close look at the Special Edition, a mirror steel finish version that has apparently become an object of desire for the computer dandy. Two years have passed since Antec introduced the P case. At the time, it was an unusual, innovative case designed to provide both effective cooling and good noise reduction for high performance enthusiasts. The P was very well received by the DIY marketplace, and despite teething problems that led to some minor revisions, it has become a highly successful product and a familiar sight in the high performance computer arena.
According to Antec, the P is their most popular computer case in Japan, which is surprising as it is a market that traditionally shuns large cases. The P is a major evolutionary update of the P The P Special Edition examined here is said to be a limited version available only through a selected number of dealers.
This is not true of the P, which was produced without any direct input on my part. The above reviews are well worth reading or at least skimming, as they form the backdrop for this article.
There is a fan mounting spot — and a supplied mm 3-speed fan — but the fan really only needs to be used with a fanless power supply or with more than two hard drives. In normal use, virtually any fan-cooled PSU should draw enough air from the front vent of the bottom chamber to keep up to two the hard drives cool.
A good PSU should also have no trouble keeping itself cool without ramping up in speed. From a thermal point of view, this arrangement is highly efficient in that the airflow of the PSU fan is used not only to cool itself but also the hard drives.
Hard drives rarely consume more than about 10W average in actual operation. This is a relatively small amount of heat to be evacuated through this free-flowing air tunnel. Following this example, in a conventional ATX case where the power supply is positioned at the top, the 75W of heat from the PSU would be within inches of the hot CPU, which could easily be producing 80W of heat. The 20W from the HDDs would also be added to the overall heat in the case, adding to the thermal load.
The arrival of the PSE coincided with that of the P, a larger version of the P which will also be reviewed soon. The two cases are shown below for comparison. The P box is big but still smaller than the P box. Lots of black ink there. What makes the P Special Edition special? It has a stainless steel exterior with mirror finish instead of the standard gun metal black.
It also has a black interior finish, as opposed to the standard metal. Mirror is certainly the right word to describe the finish of the front and side panels of the PSE. The PSE has a stainless steel mirror finish on the sides and front panel. A close comparison of the P and P specifications shows that they are exactly the same size. The P also has these additional features:. One difference not identified in the specs is the presence of new cable routing holes in the motherboard tray itself.
The sides and the front door are triple-layer composites of steel on the outside, plastic in the middle, and aluminum on the inside. The advantages of this composite material are:. There was the issue of the warping front door in the original P, which many users complained about. The original P front door was a 2-ply panel, aluminum on the outside and plastic on the inside. When the temperaure stabilized, the door could sometimes be bent back straight and straighten by itself.
At some point in or late , Antec replaced the door with a 3-ply aluminum-plastic-aluminum version with differently placed magnets. I would think for efficient cooling, you would either want a straight front to back or circular flow that would cool existing hardware and would remove excessive heat energy. I'm running a fanless scythe ninja right now, but I have thought it would be interesting to create a duct that runs between the heat sink and the rear facing fan, that way you can sort of isolate the two flows - heat from the CPU would go out the back while a general upward flow is maintained in order to exhaust hot air out of the case from GPU, etc.
While this sounds good on paper, I'm sure there are way too many factors to predict here. My theory is that the turbulent air leaving the heatsink fins will have better chance of being exhausted efficiently with this method than with the heatsink oriented 90 degrees from this angle with the fan pointing through the heatsink, up. Sigh, I wish science based software was a little more open-sourced. That would be great if they could.
I did find a software company called solidworks that had a demonstration of their CFM software with a small electronic componet.
Check'em out. I'm gonna be out of town for the weekend, but lets keep tossing ideas around. Have a great weekend. Any news? Sounds good. It will certainly be interesting if we can see some results. Joined Jan 9, Messages On my P I have the fans placed exactly as originally pictured in this thread. Works fine for keeping my E at 4. Grimmda 2[H]4U.
Joined Jul 1, Messages 3, I had to move the fan myself on my P Modular cables on my PSU required I do so Grimmda said:. I moved that bottom fan to the top hard drive bay with the included metal fan clips. However, my case is empty, because I haven't bought my other parts yet. It just sits next to me on the floor, with the plastic wrap still on the shiny panels Pse.
