CFM versus Temperature

[wafflez]

I've got a simple question so I'll try to get to the point. I have an antec p180b case, which has 2 empty 120mm fan slots in the front, and a thermalright ultra 120 heatsink with a scythe s-flex 120mm fan that pushes 49 cubic feet per minute at 1200 rpm.
I'm not satisfied with my temps. >_>.
sooo, would buying
this fan, (120mm, 110cfm, 2400 rpm, $15.99), help more if I put it

also, note if it wasn't apparent, these aren't my pics, too lazy, etc.

EDIT: I guess my real question is, would a higher cfm lower the temperature of my cpu drastically? (If it's twice as much in this context) Or should I just put it as an intake to suck in more air?

If you don't have one or two fans in the front openings I would worry about that first over the make and model cpu cooler used. One "BIG" tip for seeing all temps brought down is to get that air flow going. On the old case used for a Socket A board when that saw a 939 go in the cpu was seeing 44-46C with the board seeing upto 48C! Solution?

The old compact mid tower stylish case saw 2 80mm fans one rear one top but nothing in front and no vents! Once everything was moved into the Aero Cool model seen at http://www.xoxide.com/aerocool-aeroengine-2-black.html the board suddenly was seeing 31C with the cpu at 33C! All that time was with having a Zalman CNPS 9500 sitting on top of the cpu.

The 140mm front intake and rear 120 there helped but not as much as seen with a new build seeing the first night of 28C idle for the AM2 board with a 6000+ X2 125w model. That will probably drop down again to see the same 22C idle temp since this is on a replacement board just put in currently running for a little over 7hr. at the time of this reply.

So, the best solution to cool down the cpu and the surrounding area of the computer would be to put it in the middle front of the case as opposed to on the heatsink?

EDIT: PC_eye, I should've mentioned that my heatsink allows me to place any 120mm fan on it. Well anyways, let this thread die, I've decided to put the 110cfm fan on the heatsink and the 49cfm one in the front of the case.

After only one day with the replacement board now in the AMD AM2 6000+ X2 is constantly seeing uner 30C even as low as 21C for an idle temp. This is while the AS-5 is still on the initial breakin period usually requiring 200hrs. total.

The total air flow seen on the Antec 900 model case has the majority of credit for seeing this over the Zalman 9700 in use despite the copper base and copper finned array this model offers with a 110mm fan there. Keep the board cool to see cpu temps down low too. It works!

AHAHAHA WOW!!!
lolllll
ok, I must share my utter stupidity....2 months ago, when I built this computer, I seem to have placed the fan on my heatsink BACKWARDS, so it was simply sucking air in....I'm surprised my processor temperature stayed low even under a 600mhz overclock and technically only a fan sucking from it....I just installed my new fan + my old one pointing in the right direction, and voila! My core temps dropped 10 celcius each >_>. PROTIP: sticker side = side that air BLOWS, not sucks. well uh, I guess I can suggest the thermalright ultra 120 to anyone who needs a heatsink...because even without a fan blowing air into it I could overclock without core temps exceeding 55 degrees >_>.

The sink portion still takes the heat away from the cpu preventing that from cooking there. Actually drawing cooler air towards the hsf won't see it overheat while not seeing the results intended by the manufacturer there. Don't feel bad when the new build went together here the fan on the new Zalman was stuck into the copper fins.

You wouldn't believe the 107C cpu temp ! first seen and simply the heat felt coming from the 9700 when that was spotted when first installing Windows and the Asus temp probe along with SpeedFan. The first thought was a software glitch with one but then the other and a trip into the bios saw a fast shutdown.

The Zalman took and disipated the heat from the fan motor quite well. Once the case was opened up fast the hsf was room temp already then. The problem with the 9700 was a lack of room for the 110mm fan while the 9500 model with the 92mm fan is recessed. The motor sits on two thin metal rods that are easily twisted or bent during shipping explaining why that was seen. While that was happening the board temp was steady at 30C 1C less then seen with the old build with different brand case used.
