mean greenie????

[sendatooli]

my northbridge was overheating because my cpu fan was blowing hot air on it. so i reversed it, like it is supposed to be. problem is, i cant close the case with the fan reversed or it will blow back on itself and overheat!
so i put a larger "greenie" on the northbridge (about twice of the size of a regular one). plus i added artic silver. works fine now. but if i close the case it will soon overheat.

so my only question is, would i be better off to get a 40mm.(5.6 cfm) fan with a little greenie, or the bigger greenie with no fan? which will cool better. bigger/no fan. smaller/fan. i ask because the big one will not fit with a fan!

does a 5.6 cfm fan make any difference on a northbridge?


thank you,

thats a tough call to make....what i would do is find a 3rd greene that isnt to big and can hold a fan....a 5.6 cfm fan would make a difference over no fan......what kind of case cooling do you have? if you could keep the fan from blowing back on itself that would solve your problem and lower case temps.....can you give us more info on your rig?

Ditch the greenies!

get yourself another HSF from another proccesor that your not using or buy one mine was 5 bucks cut it down so that the fan is still on it but it fits on your MB and your set the cooler the northbridge the better. You can even set your fan on proccesor to blow down and when you install your new HSF on northbridge run the heatsink so that the cooling fins run up and down so that hot air from your proccesor does not get into the center of your northbridge heatsink yes your rite you do not want hot air moving through the northbridges cooling fins when your done it will look like this and its only 5 bucks

no cigar. i cant even fit a fan on the little greenie as it turns out.
i have a pep66 on a card. the northbridge is right under the pep66.
there is only 15mm between the northbridge chip and the pep66. and a fan will be useless if it is scraping the pep66. there needs to be a little space.
i was lucky to find a 13mm tall greenie! the ones with the fans are too tall. darn. even the fc08 barley makes it, but it scrapes the alpha. well if i have the fan pulling air off the alpha it works fine. that is how tyhe alpha is intended to work. the only problem is when i close the case even with the side vent fan going, the delta 38cfm, pumps up the case with hot air and it locks in several hours of quake3. if i reverse it, it will not blow hot air against the side of the case and back onto itself. then the problem is it blows 80 degree air right down to the northbridge heatsink.

time for a new mobo with the northbridge not right under the cpu cooler?
ahh, i love my soyo sy-6ba+100, and im poor!

oh, by the way, that picture in the attachment. that cooler would never fit under my alpha.

everything is capable of working fine here. the only thing i want to achieve is to get the case closed since the delta is so loud. i had the same darn problem with my celeron, maybe this case just sucks?(no pun intended).

any further ideas anyone has that do not included hacksaws or making the case louder would be greatly appreciated!

thank you,

Check out the tennmax tiny bga cooler.
You can find it listed on the main page under bx coolers.
Its very low profile and has a fan.
I use one on mobo and have a slot 1 with a slotket and a pep 66. Mine sits right over the greenie too and I know what you mean about no room.
Also if you have room for the fan to fit on top of the heatsink you can do this.

I do not have room thou on my system for this maybe you would.

yeah, i heard that bga is a pretty good design. still, i wonder if the large greenie i found(bigger than the bga, no fan) with the delta sucking out the air from under it cools better anyways. its too bad i cant just fit a fan on top of it. i wonder if i get that if i can blow hot air into it then? probably be even worse. i just gotta figure out how to close the case with the delta sucking as it is supposed to. im running at 144 fsb and my board only goes to 155, so im probably pushing it hard. i suppose the bga wont hurt. so i guess ill order one.

thanks,

Well if you want to get radical you can measure out where your fan is on the case cover and make a hole maybe 80mm then put a fan filter grill on the outside of the hole so it looks nice.
And if you have the kind of case where the side comes off you probably can use a plactic oil funnel and cut so it goes around the fan and have a duct.

[sendatooli]

i already have cut a 92mm hole in front of the cpu fan in the side of the case.
there is a fan attached to that hole. ive tried blowing and sucking. neither work. would i better off to just take off the fan and vent the cpu fan directly out the side?

still thinking,
sendatooli.

You need to have positive case pressure so the air coming off the fan will be moved out.
If the fan you have now when blowing out causes negative pressure then that may be why, I would think it still would grab the air from the heat sink fan thou.

i just wanted to thank you guys! i appreciate that i can always come here for good advice!
i went ahead and got the bga cooler today. installed it. mobo temp dropped 4 degrees!(also applied artic silver). the cpu temp also dropped 1.5-2 degrees! thats celcious. anyways im running my p3 700 cc0 at 144 fsb on soyo sy-6ba+100. it only goes to 155. my system wont even post above 144. still. i dont mind at all, at least 1 gig is rock stable!

so all im wondering now is do i really have to cool the southbridge and agpset and hd controller also? or is that only for extreme overclocking. i know more cooling wont hurt. but i dont want to get carried away. it is already as stable as win9x gets.

only problem is i still cant close the case. im working on that, should be fixed tomorrow. as per you guys good advice!

anyways, my cpu takes 1.98vcore to be rock stable. but hey it has been working like that for 3 monthes no problem. cpu temp 30.5c idle 42.5 full load. system 27c idle 35c full load. is that pretty good for air cooling, considering the voltage im using? oh also, the 3.3v is set at 3.58.

hey, it works great! why mess with success?
im waiting for my next whole system to start doing lots of tweaks again. so for now this is my baby.

keep rockin!,

Your temps are good.
Never hurts to cool the other chips but if your stable then no real need to.

[sendatooli]

ahh well, its not working again. 3d apps quitting. maybe my poor mobo and cpu have seen better days. well wasted 20 bucks on the bx fan. darn.
