MASSCOOL AC-PAC400

Pros: added cooling of 82watts.
can be easily removed.

Cons: sticks out the front of the computer case.

Other Thoughts: for those of you not knowing how this system works the tec hot sides heat is being removed by the top fan on the system. hwal the fan at an angle at the botem blows onto the chip puting cold air into the system. thats bacicaly all to it.

Pros: If the hot side could be outside the Case, it might give a little help.
Some might want to have the bragging rights to TEC A/C but not me, it's going back.

Cons: Knowing how TEC systems work,this system cancels itself out because the heat produced is circulated inside the Case as well as any cool air it might produce.

Other Thoughts: If this system was able to do what they say, condensation would build up on the cooling fins causing water to drip onto whatever hardware might be under it.
It's just not a good idea to air condition a Case, especially if you live in high humidity areas.
TEC CPU coolers with regulation are a good alternative to water cooling though.

Pros: I can't say a single good thing about this product. Save your money and get some good high flow, quiet case fans like Panaflo's or maybe Noctua S12's. Ther performance will be about the same if not better with the superior case fans, and most likely quieter than this shop vac, I mean PC A/C unit is.

Cons: For those of you who have already bought this and are using it, sorry to hear that. Not to say anything bad about anybody, but my guess is that those who gave this a good or better review, don't know much about PC cooling, and are probably limited to knowing how to turn their PC on and use simple software or games. I cannot see how ANYONE could give this a good review.
In theory, it's a great idea, but this unit is very poorly designed. I have read a ton of reviews on this item prior to and after my roommate getting one, and not a single review gave it a very good rating. If you take a look around at a lot of the reviews done, they say exactly what I seen happen with my roommates PC after installing this. First off, of course it takes up 2+ front slots, which, if it were redesigned, it could easily fit into just one slot, or maybe even be internally mounted with an intake extension of some type that will draw air in to it.

Other Thoughts: Second, this thing will and does not cool your PC much at all, if any. With my roommates PC, and with many reviews I read, this unit if placed in a small enough case, such as a M-ATX or a bigger shuttle case, will yield at best maybe a 4 - 5C temp drop, not all too impressive for the price. If this is mounted in a case that is mid sized pr a full ATX case, it will actually raise you PC temps, as it does not have enough power to cool a bigger case. In my opin ion after reading up a lot and seeing it in action, save your money. You can get just as good of cooling performance, and sometimes better, by simply adding better case fans to your system. And considering how loud this thing is, the case fans would be quieter.

Pros: Could be used as decoration.

Cons: Unless this product is just completely bogus, it uses TEC to create a "cool" airflow into your case. Problem is, at best it's very inefficient and at worst, it’s useless. Even if this device utilized a high wattage TEC to produce a significant cooling effect within your PC case, due to the lack of adequate cooling of the hot side of the TEC (or ventilation of the device), the temperature difference between the hot and cold side of the TEC would be small, very inefficient, and any actual temperature reduction would be at a cost of pumping out much more heat into your room than it cools your PC. That is to say, this product could work in theory; however, its poor implementation is wasteful and yields no real world performance.

Other Thoughts: NewEgg is awesome, I spend xxxx a year here, but this product is bogus. It should get a 0 out of 5.

Effective? Quiet? Usefull?... laff

Pros: cools down my case and even slightly cools down my room. my room used to get so hot from having my computer on all the time playing world of warcraft and having halo 2 lan partiez all day. now i dont have to play in my underwear cause my room is teh cool

Cons: i have very curious cats and the one (master chief is his name ROFL) decided that he would start sniffing the new ac and it sucked his hair right into my case. i rushed to see if my computer was ok and everything was except the ac it waz brokes.


oh the cat was alright too i guess

Other Thoughts: I wish it had blue leds..... man i love leds

master chief likes when i tape leds to him and he watches their hypnotizing glow. its beautiful

Pros: NONE, WAS IN A CLIENTS CASE

Cons: UGLY,USELESS,WASTE OF MONEY!

Other Thoughts: IF YOU HAVE THIS IN YOUR CASE.YOU ARE WASTEING YOUR TIME

Pros: None

Cons: Uhm, other than it doesn't work?

Other Thoughts: Real electronic airconditioners do exist. They're used everyday in the Industrial world, but they also start at around $5000 so what do you expect?

Pros: The idea of this kind of technology

Cons: This is still a thing of the future. The idea is GREAT but this version I do believe is still the "prototype" for waffer. If anything at all, this made my computer run 1-2C hotter. I do not advice this one for anyone. A safe alternative are the Zalman coolers for you CPU and GPU.....I just bought them and I will repost reviews there. I'm sure they will be 5star

Other Thoughts: I'm in a dorm and my room temp is between 75-80 degrees f

Pros: Might be good if your pc has absolutley NO venting or openings of any kind.After installed can be taken in and out as easily as a sega genesis cartridge.

Cons: HUGE,If you have a front door on your PC it needs to be open to use this,NOT powerfull enough.

Other Thoughts: This thing is huge and I have been running it on snow setting and I bought this hoping I could lower my 7950 temp.I have not dropped 1 degree idle,or max load.
This thing Needs to be around 10 times as powerfull as it is to do it's job.
It's big bulky,and needs to be redesigned with 10 times the cooling power.
It is not as loud as people say,It is just as loud as a pc tower fan.
The only way this thing would make a difference in your pc is if you have absolutly no openings or air flow.

Pros: It looks funky and adds personality to your PC.

Cons: LOUD when on the AC setting. Not too bad at all when on the "fan" setting. Milo (reviewer below) must work for Masscool (LOL). "Not loud"? Must be kidding. If you want to run it on the fan setting all the time, it is not that loud. But if you want to set it to the "Snow" setting and actually utilize the supposed "AC" function, be ready for a very loud unit sticking out of your PC. Also, this only made about a 2 degree diff in my PC. When I played games, it made about zero diff.

Other Thoughts: This is not a very efficient or usefull cooling unit. If you have a system that just needs a little cooling help, stick with case fans and/or get a better CPU fan. Your money will be better spent that way. If you have a system that needs SERIOUS cooling, then check out a liquid cooled system.
