[abu_has_the_power]

ok. i have a raidmax 868 case. here's a pic:

it's only got fan holes for 80 mm fans. i have a 120 mm and a 90 mm case fan just lying around, and i want to put the 120 mm fan into the case. how would i do that without using dremel or cutting the case in any way?
i was thinking of getting a 80-120 fan adapter, and put it in the back, but i haven't found any 80-120 adapters.

help please. tks in advance.

[Triadcool]

You could try screwing in one or 2 of the fans holes in and it would stay just fine.

but wouldn't it shake and rattle a lot?

[_John_Lennon_]

No, it probbaly wouldnt.

I have had 80MM fans just standing up in my case before, as well as suspended from the top of it, using tape (funny store time.)

Yeah, so I have the fans taped up above my case, to blow air downward onto the processor, (dont knock it, it lowered my CPU temp by 3 degrees.) so anyway, Im surfing some forums a few days later on it and all of the sudden I hear a horrible knocking sound and then a thug, lol. Well, I checked and the fan had falling and was currently trying its hardest to attempt to slice the IDE cable coming from my DVD-Rom and Cd-RW drives, lol.

Needless to say I removed it, and just put it in the front of the case where its doing a fine job, securely in place.

[Cygnuz-Y]

I think you could use a 3M tape that has both sides sticky....

[abu_has_the_power]

lol. but a 120 mm fan would be too heavy to hang like that. plus, i don't have enough space at the top. this is a mid-tower, not a full tower

I know i was just joking, you dont really want hot air being blown down anyway, but where do you have fans in your case already?

I dont think so, that tape is supposed to take 3 pounds stuff

A lot of the noise is caused by the speed of the air, not the amount of air moved. So channelling the air from a 120mm fan into an 80mm duct is going to generate noise - I suspect you would do just as well to get a quiet 80mm fan in the first place. Or better still, get two 80mm fans and run them at half speed.

Btw, having one fan blow air into your case and another fan blowing air out is extremely inefficient. It is much more sensible to have two fans performing the same operation (both in or both out) as long as there are no major obstructions to airflow. And since PS fans always take air out of the case, it is sensible to add extra exhaust fans.

i've tried to look for these, where did u find them?

and, my fans r like this:
2 fans in the back blowing out
1 fan blowing out on the side window thingy
2 fans on the psu blowing towards the back.
i don't have any fans blowing in the front.
but i'm thinking of getting a fan adapter to put a 120 mm fan next to my cpu and heatsink, so exhaust some heat. i mean, i guess it could go anywhere, just not lying around in my closet.

Solid CO2 (dry ice) has surely got to be the next step in cooling. Ok, you'd have to top it up now and again, but the big advantage is that the machine to create the dry ice could be in a separate room (or even building) so the noise is generates would be unimportant.

If you filtered the air going into the dry ice box so that it was dehumidified, there would be no condensation, I feel certain you could get away with only one fan (not counting the cpu HSF) and it probably would not need to run all that fast. A simple bit of ducting could vent the CO2 outside.

This seems a far better idea than water cooling, since CO2 is non-conductive. In any case, the actual CO2 would not need to pass through the machine, it could simply be used as a cooling agent for normal air.

I cannot vouch for the store for I never bought anything there before.

yea, i heard about that. so other than paying $13 for an adapter, can i put the fan in my pc withouth cutting holes?

Lynx, you do realize that this advice goes completely counter to what one might read on any number of modding sites?

They are always stressing the balance between the amount of air that you bring in and the amount that you exhaust.

I have been very skeptical of this as a major concern since it seems to assume that a case is fairly airtight, which we all know is hardly true.

Anyway, tomorrow I plan on trying out your theory. Should be interesting.

[Virtualbody1234]

I thought I just went though that same idea with you, clocker.

Think of it this way:

---> ---->

or

--->
--->

If each fan moves about the same amount of air then which way do you think will move the most air total?

[abu_has_the_power]

ok. thanks a lot for this heated discussion, but anyone have any ideas of putting a 120 mm fan into this case, without spending anything? i'm kinda low on cash rite now

Well, I tried to avoid posting that but abu kept insisting. :lol:

[Billy_Dean]

I have one blowing and two sucking. The blowing one runs across my hard drives. My case is cool as.

Your case doesn&#39;t need to be airtight, the amount of leakage around the joints will be negligible, and doesn&#39;t matter as long as you aren&#39;t drawing exhaust air back into the case. The other main consideration (as I know you are aware) is to make sure that there aren&#39;t any major obstructions to airflow.

With an inlet fan and an exhaust fan, you have effectively arranged the fans in series, so although you will have cut down air resistance, you are really only moving the same air twice. By having two exhaust fans you have increased air resistance, but you could in theory be moving almost twice as much air.

If you don&#39;t need to move twice the volume of air, you can reduce the speed of your fans, thereby reducing air resistance again, but more importantly reducing noise at the same time. The one thing you do lose is some of the ability to direct the air where you want it, but this is where VB&#39;s case modding comes into play. Vanes and ducts could also help, I suppose.

Edit: I found this info at the papst website (http://www.papstplc.com/features/articles/art006), and they make the quietest fans in the world.

[SciManAl]

can anyone say duct tape??? :P

it can probably help you if you are truly desperate to find a way to get a 120 to work without an adapter...

BTW i don&#39;t know if it is any cheaper but this web site may help you in your quest for fans/cooling stuff...
I have purchased from here, some of thier stuff is overpriced, but most of it is ok, they are good poeple though... (http://www.frozencpu.com)

and to be more specific here are the adaptors if you need them...
Ducts and adaptors here (http://www.frozencpu.com/cgi-bin/frozencpu/scan/se=Fan%20Accessories/se=Fan%20Ducts%20%26%20Adapters/mp=menu_search.html)

Practical, no.

Has it been done, yes.

I have read of this actually being done, I believe it was some Finnish nutcases who put it up on the web. The dry ice only lasted about 5-10 minutes, but while it lasted they were getting ridiculous temps and overclock speeds.

Winter must drive them crazy up there.

[SciManAl]

Wasn&#39;t that the group that also had a radiater for a completly submerged system in a thing a liqaud nitrogen??? they were getting negative temps, although i think they could just have one of there radiaters left in a bucket of water... (i think their climate was freezing, but mayby not)...

It&#39;s interesting you should mention that Al.

I just met a guy yesterday who is a freak for tropical fish.

He has a very sophisticated tank, pump, aeration, feeding setup, all of which is controlled by a dedicated PC. This PC is water cooled and his radiator is immersed in the fish tank. He uses it as part of the tank heating, the theory being, why not make use of the waste heat that you are generating?

I thought he was just pulling my leg, but he showed me pics of this setup and it was really cool.

The comp is cased in one of those all acrylic cases and the left side wall has several light bars mounted to it. The light bars are software controlled and give him a visual warning should one of his system specs rise (or fall) out of an acceptable range.

I was very impressed.

[Virtualbody1234]

Yeah, I had posted about those crazy finns that were cooling (freezing) with liquid nitrogen.

Originaly used to seal and waterproof munitions ;)

Was designed by the US navy I believe but after war, was found to be good for sealing air ducts. And it was originaly called duck tape ater it&#39;s evolution from cotton duck. This is just a much higher grade of cotton duck with adhesive and waterproofing added.

I am wrong more often than not... (http://www.octanecreative.com/ducttape/dthistory.html)

@VB,

I wouldn&#39;t worry too much about it. Unless you start looking out the window at all that snow and then glancing at your PC and going "Hmmmnnn..."

I&#39;m pretty sure there are support groups available.

[Virtualbody1234]

Well didn&#39;t we already talk about that subject just the other day? Putting a PC in a snowbank?


Hmmm. I&#39;m getting ideas for silent computers now. Isn&#39;t snow also a good sound insulator?

just so u know, i have my pc oced 2.4c @ 2.6. only reason i stopped was becuz my ram won&#39;t hold it, and i can&#39;t change the fsb:ram ratio thing. if i oced his comp, it&#39;ll have lights and leds, and hey, maybe even a christmas jingle every time u turn on the pc. lol

if u read my sig, my cpu&#39;s running at 34 idle and 44 when playing halo and dling at the same time. so, chances r, i won&#39;t burn the cpu

How much good did your OCing do for you?
Have you run any tests?

I am simply trying to assess the risk/benefit ratio.

Have you tried running PC Mark 2002?

[SciManAl]

i am sure it is in a post somewhere, but clocker do you have a link for PC mark 2002 for download etc?? I would like to give it a run on my test rig, mayby post the results hehehe... there has been some poeple saying that AMD are the best at overclock and those that say the pentium is, and what do ya know... i have one of each i think the results will be intresting...&#33;&#33;&#33;

[clocker]

PC Mark 2002 (http://www.softpedia.com/public/cat/13/6/13-6-7.shtml).

The free version will let you run the CPU, memory and HDD tests which are really all we care about...

Takes about 7-8 minutes.

What is most interesting ( at least to me) is the difference between pre tweak and post tweak scores.

Let us see what ya got.
