Dell current desktop runs cool and quiet....really curious what kind of heatsink and case fan are they using.
Anybody owns a Dell machine?? enlighten me please..

depend on the spec
some of them using fully cooper sink, such those optiplex 170L
some using tower sink(alloy + cooper) like my poweredge 800 server

but dunno what the brand of sink..

inside the cpu for desktop only have 1 fan.... it a big 5" fan with low rpm pulling air to proc heat sink and chipset heat sink.

Some of the Dell Desktop uses BTX design which is very freakin' cool.

I think most current new Dell system is using the BTX design... really cool, only 1 fan to blow at proc and to exhaust is enough...

I'm very impressed with their cooling BTX tower! Love the cool temperature! Envy la...we spent so much money on good heatsink and yet, dell can do it with only a proc fan and exhaust

my college's lab use Dell desktop, forgot which model but run with PD 2.8. and some time ago i managed to open the casing n see the hsf run with dual fan i assume it 12cm

what I mean is, it only have 1 fan, which blow toward proc HS (err...do I remember correctly, or it is exhaust fan which suck the cool air toward the proc and then exhaust... ) and exhaust (at front casing) directly out from casing...

wait till you see how dell packed a C2D E6600 into a compact sub-SFF Optiplex 745 case that even carries its own power supply unit.

it runs unbielevilably quiet and stays cool most of the time in normal ambient temperature

lemme take a snap when i'm in office tomorrow

edit: the SFF has hdd, DVD, and even an FDD to boot. generous 8 usb ports and even legacy parallel and serial ports. it has 4 ram banks (heck, it's a full sized mobo) and is able to run dual channel.

thier run cooler coz they not overclocked

that the main reason, IMO

most large manufacturer pc's like dell's, hp and lenovo all run at least 2 low rpm fans, one as the exhaust fan and another fan on the intake, the instake fan doubles up to cool the cpu and also the power regulators on the mobo. normally no fan on the northbridge...

but i reckon it runs cooler as their internal design draws air from outside the chassis to cool down the proc, instead of our DIY pc's which normally still draws already warm air inside the chassis..my 2 cents...

Nice...pls do take a snapshot! A bit regret not getting Dell PC,got a DIY pc instead... but heck,this is my first time buying a 3rd party heatsink (hopefully Scythe Ninja) and mounting it myself. Everything also got 1st time right, at least I learn something...

Dell SFFs have always been rather cool (in both ways). Of course by having BTX the cost is a little higher (went to see the rig on dell.com and its quite costly also)

Not really.
Remember i used to sell lots of Dell Optiplex SX280 SFF PC's?
It's kinda hot though.

dell's are quiet cos like most manufacturers (unlike enthuasiast)..... its design to operate within a certain thermal envelope... for enthuasiast... we want them as cool as possible. That's the difference.. that's why it's quiet

r u sure??i think our clone pc's got better air ventilation through inner casing......

there's this big fan with Low rpm to suck air from front towards CPU which is attached with a really big heatsink, and exhaust to the back of the casing.

see pic below.... Precision 380.

summore, the design is nice!!

wow, that's was a nice setup from dell
btw my 4500 desktop using 1 fan + 1 concentrated blowhole to suck warm air from inside. yes, it use another 1 fan for psu ;p

the SFF with a 3.5" hdd, and everything else is laptop component.

the ruler is there for comparison

it's a BTX design. 1 fan for the cpu hsf and another one for the puny 300w true power psu

notice the C2D tag there.

betcha they cant do it on a pentium d 820 system

I still remmember that dell is one of the first to introduce direct exhaust piping in their desktop series

back then most co. still fumbling with internal HSF which draws hot air from within the casing.

but too bad back then the components ran cooler
so it became a luxury item...

Maybe you are right, never try to get in detail of Dell casing... btw, Dimension series casing got little bit different... my company have 2 new Dimension just brought last year... dun ask me to take picture...I dun have camera...

Dell has been using BTX ever since they had a fair number of RMA issues after they first started selling systems using Prescott (and its relatives). BTX is brilliant in cooling, but too strict in design-even motherboard components must follow exactly as Intel specified it. This doesn't work out with enthusiast systems and especially AMD systems as the component layout is different-particularly that for AMD systems the ram is very close to the processor because the memory controller is on the CPU. And if I'm not mistaken to use BTX Intel collects licencing fees. Overall its a flop, even Intel isn't backing up the design much anymore.

Yeah, if only Intel were serious in promoting and telling other manufacturers to use BTX.
That way, BTX will be made famous.
But then, just like what you said that intel isn't backing up the design much anymore, there's nothing we can do.

I have saw the Dell computer,those run on P4 procs. They are actaully using a fan to suck out the heat from the processor's heatsink there.I didn't see any other more fans inside the casing there. The casing is the mid tower casing.But the fan is not really noisy as i think they are running at low speed only.

even Dell AMD based c521 and e521 is btx-based design. they are really cool and quiet, really suitable for basic computer usage and mild gaming

Does anybody know how fast the fans are running? low rpm means how low? How do I control my fan speed without any 3rd party fan controller?

Heh, for the Nehalem processor even intel will be in trouble. Proc will have memory controller integrated, memory will too far away from processor to keep trace length short enough for high ram speeds. To make things worse it will probably be running DDR3 which will be much higher than DDR1000..

Make sure you read though the WHOLE help file before asking questions. Its quite short, so no excuses.

I did try using Speedfan to control my fan speed. Not working also...anyone know the reason?

the fan got connected with the motherboard or not ?

Attached thumbnail(s)

with such components and features...salute
my DELL SBE servers and Dimension 3100 which inside cooling unit similar to the pic u all post, the brand of the fan,its quite and efficient...arghh memory block! forgot the brand

my dell is so silence...cannot hear the fan also...got 4 slot of ddr...running on dual channel...but the psu only 305w...i already order 80mm fan from allingap...a delta one...46cfm for exhaust...

juz wanna ask a Q...
cn i fit a normal atx mobo into a dell casing?
thanx

I didn't see any exhaust fan.
Where is it?

anybody dare to take out the giant heatsink cover and see wat kind of heatsink did Dell put in...?

Just Wondering if BTX Boards launc again in Malaysia, is there anyone inteterested in buying those units?

i think DELL is using BTX..and some of the silent fan and full copper i think.

lol.. i am using E520 ... i don't understand why is my pc fan is runnign like ... a factory..

go for dell..hehe..

SERIOUSLY.. my e520 is so noisy i don't know why.. (in an air cond room)

what ur mean..is it the fan noisy??..

super noisy indeed

so only the fan is noisy?

i got a Inspiron Desktop, using an e4400, the only has 2 fans, 1 for exhaust (nidec) and 1 on the cpu, the cpu's fan is a leaf blower at 100%, and its made by nidec too @_@

i think in a region of at least 45dBa

I wonder what's up with Dell these days.. Or are the new processors that hot till they need to run the system fan that loudy?

My old Dimension had only 1 Nidec fan and it was virtually silent.

really gangu lor if like tat..br i thnk for good coolng indeed...

hi, any external fan devise that can help cooling laptop? suggestion pls...
