my boss had me install something "COOL" today..lol

OK my boss was concerned that the server at my job was getting to hot on the inside of the case. so he ordered some stuff lastweek and i paid him no mind. he gets some boxes in today and i was like ok whats this. he give me a small box tells me install this in the server i was CRACKING UP when i saw it. have any of you PC guys ever used this before? this is my first time

 

we put those on the old HP server CPUs when their internal fans shit the bed.

 

man i am new to this but i have been doing pc repair for a while never seen that tho. it looks just like a mini radiator. its funny to me

 

Fairly basic. I'm watercooled, but my system is a lot more elaborate than that.

 

yuck!!

its one of those "entry" level water systems. he would've been better off with an all copper heatsink w/120mm fan for the money.

its a decent cooler, but not worth $100.

note: may not fit some motherboards and/or cases.

 

thats what i was about to say...if you want a GOOD cooler, youd build it yourself. i bought just about everything that dangerden.com had for sale for this dude when i made his son's computer.

he saw a desktop that i made for my friend (clean cased, water cooled, and p4 2.4c oced to 3.4ghz, stable....this was 2 years ago). and he basically gave me an unlimited budget (4k...so fo a gaming pc, that might as well be unlimited). so i took a 3.0c, 2gbs of crucial PC4000 RAM and an ABIT IC7, ATI RADEON x800XT (the only computer PART on his kids christmas list) my danger den shit (radiator, storage container, pump, VGA Cooler, CPU cooler and NB Cooler) and a lot of knowledge and had this computer running stable at 3.6ghz and far cry running at its highest frame rate and pixel depth at over 40 fps. it was hella crazy and it was one of the more fun things ive ever done. sadly, the pictures of the finished product and the screen shots of the speed and far cry's fps are all on the hard drive that has no home.

seriously. water cooling is where its at. no noise, and if done correctly, no fuss......okay the pump has a hum, but its less audible than the fans.

 

Water cooling is the shiznit. I think I'm going to take a stab at phase change cooling on the next one though- with one evaporator and compressor for each heat generating device if I can manage it. Maybe just phase change for the CPU and then water cooling for everything else. We'll see.

My case is still noisy.

 

phase change is nice if you have the money and live in somewhat cool climates. i hear its not so gravy when you live in hot places like so. cal or az. people usually change over to water during the summer months.

anyway, word on the danger den stuff. if you order from SVC.com - Computer Hardware & Cooling and use coupon "maxpcjuly" you get 5% off. they have some nice stuff including danger den and pretty good service. i also like the corsair water cool kit. i saw it for 100 at fry's for clearance, but have no money now or at the time. its basically a rebadged swiftech and swiftech is a big name with water cooling (best cpu waterblock = cascade, renamed storm).

 

You must not understand what phase change really means. It's way better than straight water cooling no matter what the outside climate is.

 

phase change is like ac for your computer.....actually, thats exactly what it is.

the only thing close to it that ive done is we messed around with some other coolers and ended up soldering a large copper pipe to the plate of one of the fanless coolers. we filled the thing about half way with alcohol and then dropped in a few cubes of dry ice. we got to 4.2GHz (p4 2.4c from the same friend that i built the water cooled system for) and it was only 42*C. Then the northbridge shorted out. luckily it was just an asrock sis655 northbridge, so it was 20 bucks worth of fun (cause the CPU was still fine). I think he is still running that same water cooled system too. apparently it is still on par with the prescott 3.4 GHz so he never saw the reason to upgrade.

 

Yup. Phase change = infinite capacity heat sink.

 

FTMFW! lol.

 

I've seen that one. Crazy, but still not going to cool as well as phase change.

 

i have never worked with liquid cooling for a pc before. so when i saw it i was in shock! i would of never thought about putting liquid anything a pc. but again thats why i am the Jr. Tech.

 

There are mini "air conditioners" that use freon to cool the CPU.. they just miniaturized it and replaced the core with a cpu attatchment. By mini, I mean a bit bigger than a good sized shoe box. That has to be one of the best real world systems I've seen lately. By real world I mean something obtainable and useable by your average home user. Not a small apartment sized super cooler.

*edit*
had a thought.. Add anti-freeze and run the raidiator/fan setup inside a freezer. Just get a dorm fridge/freezer and drill a couple of coolant hose holes through it. Use the fridge for your beer.

Ok, thats retarded, I know.

 

LOL yeah it was. it seems cool i don't think i need it for my home pc i don't use it that often, but my laptops get used all the time!

 

I've been water cooled for over 6 years now, so it's nothing new. It's just starting to go mainstream though- and that cooler that your boss bought really isn't any better than a well designed copper heat sink.

 

hmm.. maybe i dont.. to clearify, doesnt phase change = peltier cooling?.. i think theres where i got it mixed up....

 

Nope. Phase change = refrigeration. You take a low vaporization point liquid like freon and pass it over a heat source- then force it to sublime or boil on top of the heat source. That's the phase change. When a material is changing phase, all incoming energy goes into the phase change process until the change is complete- there is no rise or fall in temperature. That's why boiling water will always be at exactly 100 degrees C (or 212 F)- it's changing phase, and all the energy is going into the conversion, not to raising temperature. The temperature doesn't go up in a pot until alll the water is boiled away.

The same happens with a refrigeration system. You have infinite heat capacity as long as you don't run out of matter to phase change. If you get a material that changes phase at a low enough temperature, then force it to constantly change phase over your heat source, it stays at that temperature no matter what as long as the phase change never quits. That's how refrigerators work, and that's how phase change CPU coolers can keep a chip running at temperatures WAY below freezing.

Of course, this is an oversimplification- but that's basically how phase change cooling works.

 

Peltier cooling is just a heat pump. You have a dielectric sandwich that moves heat from one side to the other when a voltage is applied, and if you're able to move more heat than the heat source puts off, you cool the source. You do have to have enough cooling capacity on the hot side of the TEC (thermoelectric couple) to wick away all the heat from the TEC and the heat source or else you lose.

Peltier cooling is completely different from phase change cooling.
