PC is going to be operating in 100 degree temp room

You need one of these...LOL

-For real though… place it in a spot that is relatively safe and enclose it. Just leave some room for air to get in.

** Assuming you mean 37 Celsius.. You won’t have a heat issue if you run a simple work PC.
If you are slapping a quad core in there OC'd and a 8800GTX you gunna need some Water cooling.

By 100 degrees I figure its safe to assume that's 100C.

Edit: Apparently no one found the above line funny but me. 100F ~ 38C for the record. That was a prod directed towards the reluctant to switch from fahrenheit but I digress...

Harddrives are usually rated for 60C.
CPUs are usually rated for 65-75C.

These are their operating temperatures, sometimes referred to their environmental operating temperatures but that's almost a misnomer as they intend to mean the temperature of the device itself when operating in that environment, not the temperature of the enviroment around the device.

Harddrive wise, go single platter only, I'ld suggest a Spinpoint F1 if you need the storage, otherwise you can find something significantly cheaper in the smaller ranges. If harddrive access is considerable then yes, you will need to invest in a cooler, most likely active (fans).

CPU wise you're probably best going for an E1200/2140/4300/6300. Anything beyond that will probably be a nightmare for cooling.

For the most part the motherboard(integrated video?)/power supply/etc should be fine with those temperatures.

I would suggest either getting a chasis with replaceable or washable intake filters as well. Exhaust filters are usually more of a hinderance than anything.

I'm guessing this PC somehow integrates in their POS system? If the storage requirements are meager ie if its a client/server system you can pickup the smaller transcend SSDs in the 4GB or less rage for quite cheap, the caveat is they are in the 44pin ide notebook factor and you will need an adaptor, and of course a motherboard to boot off of IDE instead of SATA.

Good luck.

Generally speaking your machine will run 15C hotter then room temp. so if you are 37C, count on this machine idle @ 52C, well within limits as long as you don’t push that machine.


***edited spelling

I guess one of the main questions determining the parts is what is it going to be used for? Browsing online/ running some type of recipe/payroll software? I'll assume not playing games...

Water only boils at 100c at sealevel. Maybe he means 100c 5000m under sealevel?

Wolfdale + SSD Hard Drive + Watercooling.

oh yes.

Good luck dude. Make sure you drink a lot of water to keep your self hydrated. Your best bet is a TEC cooling set up. 100C is the temp in which water boils! 100F is 37.7C, then normal water cooling will work. Yes I know that you are talking about 100F, but thats still pretty hot. My basement is at 68-75F during summer and lower in the winter.

praeses, did you fail science class?

Your assumption was flat out dumb. Working in a room at 100 C would kill a person. Let alone anything in the kitchen with water would boil away. So unless the whole kitchen is a giant oven go back and pass elementary level science.

Back on topic people. Robrich, I would suggest that you definitely get filters over all of the fans on that computer. The grease and flour in the air will kill it faster than you would believe. As long as it won't be used for gaming or something of that sort a E2140 would be a really good choice because it wouldn't need a very high flow ventilation setup, which would cut down on clogged filters. You could even use a passive cooling setup with no fans and a large CPU heatsink, which would mean you wouldn't have to worry about making sure that the filters get cleaned.

Not true. We are so over taught Fahrenheit, that any unlabeled temperature is perceived to be in Fahrenheit. Now, as smart as we Americans actually are, we realize that the rest of the world uses celsius, so we automatically assume that any unmarked temperature is in celsius, also assuming that the poster is not from America.

However, when I looked at the temperature, I assumed he meant Kelvin, as it requires no temperature denomination. -280degrees F might allow for some sweet overclocking, though I probably couldn't resist licking the CPU,only to find my tongue stuck to it, which realllllly is a bad position to find yourself in when you are the only IT person in the Arctic Research facility (aka IARC www.iarc.uaf.edu/).

wow. people are way over-thinking this one. no environment where a human works NORMALLY will get to 100C. are there any budgetary constrains? what is the primary purpose of the machine? you can get an IDE <-> CF adapter with a 4GB media on it, and use a Celeron 440 (conroe-L 35w) or an Athlon 64 LE-1600 (45W) with a BIG heatsink like a Coolermaster Hyper 212 with the fan remove. Just eliminate as many moving parts as possible and only use fans as a means to exhausting the hot air. It's possible to optimize an XP intstall to fit on that CF card with the page file, and so long as nothing is saved to it, it should be VERY reliable, even in that sort of environment. load it up with a gig+ of samsung or micron ram (try and find some ECC ram and mount heat spreaders to it for ultimate stability, and use only one stick)

this wont be a speed demon, but after it boots, it should be more than adequate for inventory or ordering supplies. Get a High-speed Patriot or Kingston CF card @ 8Gigs if there needs to be some applications installed outside of the OS

100C=212F at sea level

100C lol

The biggest problem is going to be the combination of dust (flour) and moisture/grease, the machine will require regular (probably daily) cleaning; a case with removeable (and spare) air filters is a must.

Have you considered the "Public Health" side? Having a PC, keyboard and monitor in a kitchen area would be a major breeding ground for all kinds of nasties (Specialy the keyboard).

Or build a column and put the computer(s) in it, and give it its own air duct.

No, no, people, you have it all wrong!!! By 100 degrees, he means 100 Kelvin, which translates into -173 degrees celsius or -279 degrees fahrenheit. I would suggest to the OP that he makes sure to bundle his computer up in a nice comforter in order to make sure the cpu doesn't throttle up in an attempt to avoid damage. This technology, known as 'thermal throttling' is used in order to protect the CPU, such as in this extreme case where the CPU may get frostbite, which can/may develop into gangrene.

I thought before I posted, but I just think in the wrong direction.

Water cooling doesn't require water. Sand perhaps, is a better replacement.....

Yes...

Sand.

It doesn't matter, like I said much earlier, he means 100 K

No. Kelvin. Just accept it. The freezing cold makes the food taste better.

Stemnin, you got your program wrong. you must convert 100 k into distance before you can convert it into Fahrenheit. It should come out to 78F.

Zalman used to make a pasively cooled case (no fans), the whole case was a big heatsink with heat pipes to fit a number of MoBo's; don't know if they still make it, it would get round the dust/steam/grease problem.

The other alternative is an industrial ITX PC (depending on the processing power needed).

Think touch screen flat panel. here is a site that makes computers designed for that kind of enviroment. http://www.frontlinesystems.com/products/index.php You can still always just build a box and use a touch screen also.
