Is this wise???? - Page 2

These 120mm Fans have me perplexed, the ones i've seen are for connection inside the PC, Is their no mains powered fans I could maybe fit? IE; Direct via a plug. Also what would they need to be, extractor or one that sucks air in to the unit itself?

Cutting a hole in the side is a big no no, but theres even less space on the right side against the wall and the left side will have another unit against it.

I'd just take the back off at the moment. Atleast that will let some heat get out.

Most fans you can turn either way, either to suck or to blow.

I wouldn't recommend removing the back. A lot of these cabinets use the back as a support to stop the cabinet moving. Looks like this cabinet might.

Its a sturdy unit, the backing is only cardboard type stuff anyway, it would hold, but it will be jointed to another unit for stability and a worktop fixed on top and to the wall, no way thats comming down

I would advise getting as much ventilation as possible with air free circulation, this will also any save components heat stress which could lead to a loss of service or even a fire.

2x 120mm fans opposite ends of the back of the cabinet, one at the top one at the bottom, set one to suck air in (bottom of the cabinet) the other to blow air out. As for the power supply for them, a 12v adapter will run them without a problem. the top fan to remove air as heat rises, this will establish a circulation of cooler air in the cabinet.

btw Thanks for the printer

wish I thought of that lol

when i had my old case and was using air cooling i had to have a desktop fan pointing at the front, of the case so that there was air being drawn in to the case from the front because i had it in a computer desk with a cabinet type thing which only, has side panels no front or back my pc was overheating but when i put the fan there it didn't overheat.
is there anyway you could fit a desktop fan in there where it can pull air in to the cabinet and then have say a hole at the top of the cabinet to expell the air?

easiest way i could think of is if there is a part of the cabinet that is not going to be seen, then cut a hole in it place the fan there drawing air in then cut a hole behind the pc or something to expell the air.

well it certainly looks that everyone agrees with my idea lol lol

No worries (Printer) Not ordered curry yet.

I am totally useless with electrics, do the fans come with a special adaptor? does it involve any soldering or anything, last thing i need is all my stuff going up in flames.

I've ran some base tests for the processor with the unit open at the front at different times.

I still don't know whether these measurements count or not.

Anyway, the stats for 4 processors during the evening.....

(See Attached)

2100 time = When I ran world of warcraft, which is common for me, the 45 upwards is in degrees C, is this too high?

PS - Using TAT to measure processor temp

Seems alright to me, but wouldn't it be better to upgrade the fan from the default dell one? maybe give it a bit more - taking the case off might help, but may blow up all your parts

I have also heard that you may be able to automatically turn your computer off if it gets too hot, this may be found in bios.

What about HD temps? It's those I'd be most worried about. Cook your HD and it's bye-bye valuable, treasured photos and mementoes you'll never get back. Ever.

IMHO, PC cases are designed with fairly specific airflows in mind - in at the front, out at the back (mostly!). Indeed, Intel and AMD's airflow guidelines often start in that sort of area. Being a Dell it's possible it's BTX also, which has a definite front-to-back design. If you go whacking it in a cabinet, it'll just sit recycling all its own air, getting progressively hotter until it starts to do 'weird' things, like randomly crashing, corrupting data, or killing the HD.

If you're doing it to tidy up the place, then I'd say just take the back off (or at least have a nice big opening across the back at the top), and make sure there's some air entry points low down - remember, heat rises, so if cold air can get in at the bottom easily, the hot air will find its own way out at the top.

Some hardware is warrantied up to quite silly temperatures these days - I've seen 75 degrees C mentioned in places. Thing is, that's often in environments where you have redundant hardware, i.e. RAID arrays. Throw a disk, no big deal. Besides, it's all backed up on tape/disk elsewhere, so no biggy.

It's a big biggy if it's at home, on a single disk.

I think I'd just probably take the back out of the cupboard, that should let plenty of air move around without affecting how it looks once the doors are closed.

oops just read KingDaveRa's post all the way though, i blame the Hobgoblin, mighty fine ale
