Screens- 3 ASUS VN248H-P IPS 1080p screens mounted on a stand, some old tv on the wall above it. Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat Screens- Acer preditor XB241H (1080p, 144Hz Gsync), LG 1080p ultrawide, (all mounted) directly wired to TV in other room A little, but not gobs.Gaming and HTPC (reparations)- ASUS 1080, MSI X99A SLI Plus, 5820k- 4.5GHz 1.25v, asetek based 360mm AIO, RM 1000x, 16GB memory, 750D with front USB 2.0 replaced with 3.0 ports, 2 250GB 850 EVOs in Raid 0 (why not, only has games on it), some hard drives The fan motor, in comparision to the processor, does not suck that much juice, so I expect that it won't change battery run time in a big major way. So like any hardware hack, YMMV and you are taking a chance of doing permanent damage to the machine.

Whoever did the software better realize that they are messing with the thermal management system and could seriosly fry their computer, if they set things up to not cool enough. Presto! Variable speed fans dependent on how hot the microprocessor is!īefore that, all the PC's had fans that ran full blast 24-7-365. That number gets dumped into a DAC, which becomes the voltage for powering the DC motor fan. (SMA,SMB, I2C, the original was SMA if I remember correctly) A software routine reads the temperature and makes the call "cool me off" or "at desired maximum temperature" which gets turned into a number that gets loaded over the bus back to the TAFI chip.

The temperature is available for readback over a serial bus. With some signal processing, you can turn that into a temperature number. The forward biased voltage of a diode changes with temperature. How it works (the simplified 2 mile high view)- Sitting over inside the microprocessor is a diode, that is at the same temperature as the microprocessor chip.
This widget (or a variation on it) now sits inside every PC/Mac/Laptop/Desktop box on the planet that has variable speed fans, that cool on demand. I designed the chip for something called TAFI (Temperature and Fan IC) a way back. Not 36 hours ago, I left my MBP at the Apple store for them to fix the heat problems. I'm just a bit irked that Slashdot posted this today. Varies by fan of course, but this probably won't drain your battery any faster than plugging in a flash drive and pulling a few files from it. Notebooks, on the other hand, tend to use very small fans such as 40mm units, which have a power draw in the half-watt range at full tilt. There are fans out there that draw 12w and up, but those tend to be the high-speed 120mm fans that can do serious damage to objects that happen to get in their way. I've seen numerous desktop-sized fans that use quite a bit more power than a notebook hard drive, which (in my experience) draw 2.5w or less (ie, you can power them from a USB port with no extra plugs). The voltage control almost certainly works on a percentage, but even if not, there's only so much available to give it - you can't just pull random extra voltage in from somewhere to overvolt the fan.Īs to the relation to a hard drive. The app just overrides the software control telling it to throttle the voltage until it hits near a certain RPM. It usually takes 5-6v to get them spinning and overcome inertia, but after that you can drop it down to 4v or so to keep it going. Some people who use their laptops as DTR machines will have them under a constant heavy load (and then run folding in the background, just to make sure their batteries never stand a chance), and their fans aren't tearing themselves apart.īasically, fans can be fed anywhere from 0 to 12 volts (maybe laptops are 0-5v, but it's pretty standard).
The software won't throttle the fan faster than it was designed to go, and all fans are designed to be able to sustain their maximum rotation speed until they reach their MTBF. Well, desktop fans have yet to rip themselves apart.
