Just ensure there is enough ventilation (remember air has to get in also, not just out) and that you can access the power button, DVD, USB ports, etc. A 3 sided box is by definition open at the front, rear, and bottom, so front panel access is not an issue. Maybe, maybe not. It depends on where the box is placed. Making access holes for these without compromising the sound dampening is probably the hardest part. Not at all. The goal here is not to make the workstation completely silent, but to decrease the SPL of the mid and high frequencies to little more than room background noise level at the ears when seated in the desk chair. An acoustically damped 3 sided box with small front/rear overhangs accomplishes this, in the two ways that matter: Again, maybe, maybe not. There are many variables here. In some cases a 3 sided box will have very little effect; in others a great effect. 1. The damping material, whether carpet or acoustical egg crate foam, absorbs most of the mid and high frequency sound energy generated by the fans. These sound waves normally radiate not only out the front/rear case vents, but also through the thin sheet steel and plastic panels which tend to resonate at or near these frequencies. In the stock configuration the fan noise radiates in all directions, but not uniformly. If the damping material is in the correct position that a significant amount of the sound strikes it. They *may* come through the case - but they may not, also. And if the plastic panels on the front are resonating, damping material on the side will do little good. 2. Because the sound pressure level of mid/high frequencies drops at a much higher rate off axis from ear position, any sound energy at these frequencies not absorbed by the damping material propagates at floor level out the front and back only. Again, too many variables to make such a statement. Location of the box relative to the ear, reflections from walls, floor and other objects in the room, etc. By absorbing most, then directionally focusing the remaining mid/high frequency waves, which are now of greatly decreased amplitude due to the damping material in the overhangs, the noise is barely audible while seated in the chair. You must kneel down to floor level to really hear the fans now. This solution works without compromising access to the machine, or compromising cooling capacity. The T7610 is a true business workstation, with front-to-back only airflow. This 3 sided damping shroud will not work with PCs which have side air intakes, top exhausts, etc. This should be common sense to everyone, but not everyone has common sense, so I'm attempting to head off further me too posts. Again, they may or may not be decreased by a three sided box. There are many variables. And no, you're not attempting to head off me, too (note the comma - it is required) posts.

fancontrol wheezy Dell T7610
Hi, I recently bought a workstation to do calculations. It has two Xeon processors with 16 cores and 32 threads in total. I realized that the temperature gets very high on high load typically 80C. That is way too much. Then I changed the fan speed in the bios from auto to high. Now temperatures are reasonable 45C, but it is very noise and it never stops (even with no load) I have to reboot the computer to change the fan speed.. I would like to use fancontrol but I get: /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed It seems that lm-sensors do not read properly the fan. I get: Adapter: ISA adapter Physical id 0: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 0: +38.0°C (high = +79.0°C, crit = +89.0°C) Core 1: +37.0°C (high = +79.0°C, crit = +89.0°C) Core 2: +40.0°C (high = +79.0°C, crit = +89.0°C) Core 3: +38.0°C (high = +79.0°C, crit = +89.0°C) Core 4: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 5: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 6: +41.0°C (high = +79.0°C, crit = +89.0°C) Core 7: +38.0°C (high = +79.0°C, crit = +89.0°C) coretemp-isa-0001 Adapter: ISA adapter Physical id 1: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 0: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 1: +40.0°C (high = +79.0°C, crit = +89.0°C) Core 2: +42.0°C (high = +79.0°C, crit = +89.0°C) Core 3: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 4: +44.0°C (high = +79.0°C, crit = +89.0°C) Core 5: +40.0°C (high = +79.0°C, crit = +89.0°C) Core 6: +42.0°C (high = +79.0°C, crit = +89.0°C) Core 7: +45.0°C (high = +79.0°C, crit = +89.0°C) I edited /etc/default/grub and added GRUB_CMDLINE_LINUX_DEFAULT=quiet acpi_enforce_resources=lax as suggested in http://hydra.geht.net/tino/howto/linux/fixes/w83627hf/ But no success.

(not clear from what you wrote) Dear Ingmar, Thanks for your answer I didn't open the computer. I do not know if the fan connectors have 4 pin. I prefer not to open the computer. It is on warranty. I run sensors-detect, but no success. It only finds coretemp. The option that I added in grub was just to try something. I found out that I can control the fan with i8kutils. I can turn it on and off, but I can not use it with fancontrol. I would prefer to be able to use the fan with the standard fancontrol but at least it works. The drawback is that I can not control the speed. Thanks, Dan

Is it the CPU fans or the chassis fans generating the intolerable noise? If just the CPU fans, you can simply replace them with quieter models. If your system accepts wide coolers, two of this model would be suitable http://www.newegg.com/Product/Product.aspx?Item=N82E16835114120 If it accepts only narrow coolers, then two of these http://www.newegg.com/Product/Product.aspx?Item=N82E16835114142 The 8 core Sandy/Ivy bridge Xeons range from 95-150 watts Thermal Design Power, or 180-300 watts combined for a 2 socket system. The stock style fans required to evacuate this amount of heat, plus that of the GPU, HDDs, system chipsets, DRAM, VRMs, etc are not going to be quiet. Dual socket/professional workstations are generally not very quiet machines. Beyond replacing the CPU coolers there are a number of ways to reduce the noise while still achieving the required airflow for proper cooling. Run the fans at full RPM all the time, while damping the interior of the chassis using acoustic damping pads such as http://www.acoustiproducts.com/en/acoustipack.asp When applied correctly, thoroughly, to all interior surfaces, this will absorb much of the high frequency fan noise emitted by the CPU and chassis fans. I don't use such self stick thin foam pads as they are over priced and the performance isn't that great for the money. I use 1.5 acoustic egg crate foam attached with 3M Super 77, as the egg crate foam yields superior acoustical damping performance. http://www.parts-express.com/acoustic-sound-damping-foam-1-1-2-x-24-x-18-ul-94--260-516 This is the material used inside of speaker cabinets and recording studios. The self stick thin foam is much easier for most people to install which is why I mentioned it first. You can also use a manual fan speed controller such as http://www.newegg.com/Product/Product.aspx?Item=N82E16811999171 This allows you to fine tune noise level vs cooling performance using continuously variable knobs. This requires replacing any existing PWM fans in system with non-PWM fans if using a standard fan controller. There are some PWM controllers on the market but I'd avoid them. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

If you don't want to void the warranty, then don't monkey with the fan speed or accidentally shut any fans down for any amount of time. That can roast things. There are companies that sell sound killing computer cabinets for tower style computers but they're not cheap. Google is your friend. You don't strike me as the handy type but I'll suggest the most common inexpensive DIY path taken for killing PC noise. This assumes the T7610 sits on the floor next to your desk, not on it. If not, put it on the floor already. Build a 3 sided box out of 3/4 MDF with outside dimensions, matched to the T7510 11W x 18H x 28D Cover the inside and outside with low pile carpet, using 3M Super77 adhesive or simply lots of T50 1/4 staples. Wrap it around the edges and neatly trim it so it looks half way decent. Lower it over the T7610 so you have 3.5 overhang front and rear. This will pretty much kill the noise problem instantly. Carpeting the outside isn't necessary for killing noise, but looks better than bare MDF. You could use black synth wood grain Melamine or even Maple veneer if want it to really look fancy. Finish is your choice. You could substitute 1.5 thick egg crate acoustic damping foam on the inside. Carpet remnants are usually easier for most people to acquire from a store or relative/friend, probably cheaper as well, and just as effective at killing the noise. I've build a few of these in the past and they just work. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Noise from the computer will be the least of his worries :) But seriously, you are correct. Encasing the tower in a sound dampening box works great.
