How to power a 12cm fan from an Eee PC 701 4G?


So I have a Eee PC 701 4G (only the motherboard!) and I don't have any cooling on it. It's a 900Mhz CPU so I think it needs cooling!!


How can I power my 12cm fan from it? I tried it powering through two USB port, but the fan is too slow.. (maybe because it gives 5V and the fan would need 12V?)



Answer



I know your question asks re a 12cm fan, but that big may not be necessary. See how hot it gets.


If you did want 12cm, you could power it from the mains/acdc.


For example any USB-SATA/USB-IDE adaptor comes with a plug with something like a 4 pin molex or similar,like a sata power connector. So, either way, with 12V, and the fan can connect to that whole plug, it may need an adaptor but they're easy to get.

Laptops tend to have small cpu fans. alternatively, there is this option(I see it titled mini vacuum air extracting usb case cooler cooling fan). Looks like it goes adjacent to the vent. But since you have just a motherboard you could blow it elsewhere. Just onto the hot part.


If there's a metal plate over the CPU that takes heat, then you would blow onto that.


I'm not sure how you'd do that with a blower on the side - maybe build a tube to redirect the air (let me know what you'd use to do that if you do). Assuming the CPU is on the bottom of the motherboard, you could raise the laptop a bit and blow the air under it from the side that may do it. Or, use a fan below it as you seem to plan to do.

You can also get a more typical laptop cooler, a laptop cooling pad, some have a big fan like 14cm.. pluscom do a 14cm one and they do a 12cm one.. The description says Aluminum USB Notebook / Laptop Cooler 12cm Fan with speed control Switch & 2 USB ports So, it is able to get its power from 2 USB ports. You can get ones with 3 small fans too. All USB powered no ACDC adaptor.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
