I have a Thermalright SI-97 (http://www.tekheads.co.uk/s/product?product=604126) CPU cooler.  How best should I mount the fan; with the fan pulling air away from the grill/CPU or blowing through it and onto the CPU/board?...  :?

Mine blow onto the board but cools my northbridge at the same time as its got a heatsink on it, no fan.

Just try both, let us know how you get on  ;)

whatever floats your boat :p

best if you can havce a duct somewhere, so the hot air is ducted out of the case.... or your sucking cool air in through it ;)

Personal preference is a duct into the fan and blow onto the CPU. It may increase the heat inside the case slightly but the processor needs cooling the most.

...just what I wuz a thinkin. ;)  Do Tek sell ducting? :) [/looks]

Still as messy but Ive removed most of the bulk from the centre of the case.  At least the air can circulate now with most of the wiring out of the way/welded down...  :mrgreen:

The pipes on that thing feel really cool - is that normal? :shock:

Case Temp: 28/29Ã,° (Was in the mid 30s with Aero7)
CPU: 41/42Ã,° (Was in the late 40s with Aero7)

While Im here, I whacked the CPU fan in via a rheostat but it dont seem to be changing the speed at all?  Any ideas?

:)
Ã, 

they must be the inlet pipes onto the hsf :D

remember heat pipes flow!!!

hows you got it wired in ? I presume theres only one way tbh, fan - rheostat - power

not much to go wrong tbh, unless the rheostat is nackered ?

did you try the speedfan program ?
itll do your fan speeds automatically for you depending on temp :)
...I know most programs like that are a slow resource hogging PITA, but that ones really good :)


p.s. pics... looking good now :)

Ã, 
Im gonna try that now.  How does it change speeds?  Does it change the volts?

Recipe for disaster in my hands!  :twisted:
Ã, 

not sure how it changes the speed tbh.... its a built in function of 99% of new motherbords... it just acceses/takes care of it for you :)

theres probably some settings in the bios you could use... but you have more options with that program...

you can set different speeds for different tempretures..
so really quiet what its idle/cool
little faster when its warm
belting fast if it gets hot

(or you can set a desired temp and itll do it automatically ;)

Quote from: knightyor you can set a desired temp and itll do it automatically ;)

Thats the best way of doing it IMO.

not really, as it will bounce the fan on that temp, get to 1 deg above it speeds the fan up, then down to target, up,down,up,down.

Sounds like a boy racer revving his 1.2 punto at the lights.

Well its fine on mine. :D

Well, when you get a more powerful PC.......

mines an 2500 running at 2200mhz. telling me thats not powerful enough to generate heat??

Ã, 
24hrs-in and everything seems tickety-boo.  No CTDs in gaming either! :nana:

...but the noise from my stock Northbridge fan is driving me berzonkers.  Whats currently de rigeur for Northbridge coolage? I dont mind a fan type again as long as it can STFU!  :mrgreen: Will consider anything, tbh... price no prob.

Can the old NB fan be removed without having to take the mobo off? (can the pins be snipped?)

:)
Ã, 

think youll have to pull the board out to get the old one out and stick something like a big passive zalman NB HS on there tbh.


BTW Brummie, your on a mobile CPU, unless your running at stock desktop voltage (mobile = 1.35 or 1.45 / desktop 1.65v iirc) it wont be putting out nearly enough heat as eagles XP3000+ for instance.


the motherboard cpu temp controller narked me tbh and i left it on at full speed as the change in noise drived me nuts, especially when trying to get to sleep, I could physically hear it stepping up two steps then maxing out then stepping back down.


Blowing down is usually best as it blows over the mosfets / NB (which youll need if you run the NB passive)

Id second the big ass zalmen passive n/b heat sink... put your CPU fan blowing twards the m/b and that shoudl cool it plenty :)

as for the fan speed programs... I know what you mean about those other programs, but speed fan kicks ass, it will gently inrease/decrease fan speeds by 1% at a time :D

and tbh, with good case airflow and a nice cool case that new HS should keep the cpu nice and cold :)

(p.s. no i didn;t write speed fan, and im not on commision :( )

Ive installed it but man, its confusing for me... :(

It aint far off me normal 2500 TBH

Another option is to install a 120mm fan in the side of the case blowing directly onto the CPU/graphics card and a similar sized extractor in the top of the case.

Thats an idea - I have a 120mm Akasa lying around.  Whats the best way to cut out the hole?

Btw:
Star Wars = Geek ;)
Star Trek = Nerd :P

Last time I did it I used a jigsaw with a metal blade after marking it out, did OK but there are other methods.

buy a case with hole in it :D

mmm, if its cool and quiet leave it.... otherwise like serious said, get a jicksaw and cut out the hole :)

you can get some edging to cover the sharp edges... but instead if buying some, just get saome smallish cable, (power cable) strip the end, then pull the wires inside appart so it splits the insulation.... take the insulation and where its split you slot it on over the sharp edges ;)

Dont bother fitting 2 fans above the CPU... its wasted airflow.

You just increase pressure, its not as effective as just mounting it as an exhaust fan, at the top of the case... or to your hard drive bays

i always go for Blow :)
