fanless Intel Pentium D?

well i already have a Pentium d 3GHz socket 775 with Antazone as-c1000 heatsink, but i wanted to know if i can run the cpu without the need of the cpu fan and the heatsink only. if i can then how?

if i can do this instead, can i just just a normal case fan to replace the hsf?

i don't want any damage done. becasue to me i think it's the hsf that is messed up witch is why it gives me random temp readings of 100c. yes i fixed it, twice :(  the reason why i'm sking this is becasue my fan right now is blowing downwards towards gpu and the top fan is blowing upwards, out of the case so the 2nd top fan pretyt much has like no airflow. i wanted the cpu heatsink blowing either upwards or to the back so it's not hard on other fans but i wanted to know if i could just use a stock case fan to replace it without problems

Fan Required, but only if you turn your computer on.

Unless you plan on doing some cooking with your computer I strongly suggest keeping the fan !!!

then looks like my only option is flipping the fans sides since i have cpu fan and case fan on heatsink cause i was able to add another, ohwell, i jus don't know why, but when i put the heatsink blowing out towards back it starts with 100c ****, i'll try jstu flipping the fan sides without taking off heasink c what happens

LOL yea that pentium is based on the prescott core that runs very hot even with the stock CPU fan. so if you want a nice big fire in your case then get a fan. The last CPU`s that didn`t need a fan were back in the 386-486 days

Remember the Petium D is a good core for a space heater, most rigs using them can keep a cold room quite warm in the winter months. Not only do you need a fan, but you need a big-@$$ heatsink to go with it. You can't replace that CPU so you don't have something that's almost a fire hazard?

Not true, I had a PentiumII 450Mhz that was passively cooled.

I have a Pentium D 925 with stock heatsink that idols at 38C and only goes up to about 50C on full load. The stock heatsink is actually smaller than my E6400 stock heatsink. I've had it running 24/7 for 1.5 years, and it's been great.

with Dougx1317. i have exact same cpu but like i said, using antazone fan, it's cause i think the fans messed up and that's prob why it was giving me 100c temp readings. with this cpu heatsink i have the cpu fan and a case fan on other side with top fans to help even more. my cpu usually runs at 30C in game i'd say 38C/40C. you cant' say it runs hot there, i even tried with just the heatsink without fans on it and still ran cool enough. if you call pentium d a heater, think about it this way, my friend has a p4 and his pc heats up the whole upstairs. and the reason i asked is cause i wanted to know if i could just use a case fan instead. also, how do cpu's with lcs run without a fan eh, no need to plug somethign in the cpufan pins, if so, tell me .

I think my VAIO that came with a pentium D came with a Sealed liquid cooling heatsink system. Maybe it had a fan but I don't think it did...

wow even my old pentium 75Mhz was actively cooled :p . although the fan barely moved any air at all. and my pentium overdrive 180Mhz actually had a fan that was built into the chip. you couldn't remove it from the top.

Is underclocking an option? I know that's a ridiculously hot CPU, but surely that would help towards the OP's goal?
October 24, 2008 8:01:47 PM

What about a TRUE? Shouldn't a cooler like that be more than enough to handle the thermals fanless. You can use it fanless on a quad core as long as you don't overclock.
October 24, 2008 8:35:03 PM

I've tried underclocking several CPUs and GPUs, and it never helped more than a few degrees.
October 24, 2008 9:08:55 PM

Ok first you need to fix your air flow problems.
It should go front to back, bottom to top, in to out.
Next get a good HSF I recommend the Arctic Cooling Freezer 7 Pro.
October 24, 2008 9:23:44 PM

Stock cooling should be okay with proper airflow - I also recommend to reval your case fans.

I do have 3 P4 machines that are servers...they keep my storage room warm in the winter so I don't have to. And I mean it.

And I've seen PII 233MHz passive, but not as high as 450!
October 24, 2008 9:59:36 PM

ok i don't know why but your all almost off topic. the question was if i can take off the cpu fan form my hsf and switch it with a normal case fan and plug that instead. and my heatsink alone with no fans does great cooling as it is, the fans r just extra boost for airflow. but 1 of em came with it.
October 25, 2008 2:20:31 AM

Most G3s were passively cooled. including the 600 mhz ones. The 1ghz and under G4s could also run passively. Mac put a fan on there anyway though.

" the question was if i can take off the cpu fan form my hsf and switch it with a normal case fan and plug that instead. "

YES!!!
October 25, 2008 3:38:26 AM

Just make sure that the fan blows in the same direction as your regular case fan and you'll be fine.
October 25, 2008 1:50:54 PM

well taht was handy. i always taught cpu fans had some sorta data being sent or somethign like that. well atleast i can get 2 of the same fans on teh cpu heatsink. .now t wait for ECS to give me a reply on why the hell everythign goes slow when i copy from/to backup harddrve
October 25, 2008 11:31:00 PM

If the fan connects with the 3-pin header on your motherboard, then it will send data about how fast the fan is spinning (RPM).
October 26, 2008 12:42:09 AM

well i ment like somethign different in the data but meh, whatever, case closed :p  side, both front are intake. both top and back are exhaust. the 2 cpu fans are blowing upwards with the back top fan, so exhaust.

100ºc = you didnt mount the HSF correctly

your initial post is unclear and not structured correctly as it seems so excuse the off topic posts

the hsf your talking about - your best bet is one fan blowing into it, and if theres a second - use it to assist and on the opposite side mount it in the same direction to draw out the heat/hot air etc

and no - you need a fan - thats not a passive design, there wont be any air flow without the fan and no way for the heat to escape - it will warp the plastic after an hour and cook the regulators

and pentium d's may i add bake the vrm on the motherboard - aftermarket coolers can do alot of damage because there not cooling the motherboard with it (the stock "spirial" coolers cool the cpu sufficently ASWELL as the surrounding VRM and chipset)

ECS btw is a poor motherboard brand at best

transfer speed issues - using vista SP0? DMA enabled? cache writes enabled? insufficent ram cause disk thrashing? wrong HDD configuration? faulty HDD? all i know it it definitly isnt ECS's problem especially when the board is out of any sort of warranty/support, and this is ECS we are talking about - "what support?"

oh and btw an E6300 (1.86ghz, 1066mhz fsb, 65nm "65w" class) CPU can barely run passively (100% load) - no chance with a 130w+ Netburst cpu like yours

My dad's crappy dell has a P4 2.4ghz in it and its kind of passively cooled. There is a large heatsink on the processor and then there is one fan on the back of the computer with a shroud going down to the heatsink.

I had a Pentium D melt into my mobo using stock cooling + fans. I wouldn't even consider a Pentium D without a fan.

I have the same thing in my old Dell. Pentium D and all it has on it is a big Heat sink. There is a shroud that directs the airflow from the front of the case under the shroud out of the fan on the back. The rear fan runs all the time and I've been using this computer for at least 4 years now with no issue. I guess you could do it that way, if you are absolutely cheap and looking for a way to make a quick buck on old mobos. Oh wait, your not Dell.

Yes you can!
Put your pc into a larger sized aquarium, make sure that all the wires are fixed well.
Buy 100 litres of sunflower oil, fill the complete aquarium with it and voilà you have a oil cooled pc!
Since oil does not conduct energy it should be possible...
