What the....????

[JimmyG]

I put a 120 (60cfm) blowing in at the bottom front and a 120 (60cfm) blowing in at the CPU HSF (Swiftech MC462) in the side panel. There is an empty 80 at the top rear and a double 60 bay cooler (40cfm) blowing out at the front top. I can feel air blowing out the empty 80 in the back.

I'm running a T-bird 1.33 at default speed with 133 FSB on an ASUS A7V266-E. I'm using rounded cables and have a wide open air path thru the case. See my sig below for the rest of the hardware details.

Max CPU temp is 47C at full load and 43C at idle. Removing side panels make little difference. Ambient is 22-24C.

I repeatedly see people claiming sub 40 temps with lesser air flow and lesser HSFs. I even popped for an SK6 HSF and it didn't work as well as the Swiftech.

What gives???:confused:

your ambient is quite high (compared to mine) also your mobo temps may be off slighty, there are so many variables it is hard to list then all, make sure you have applyed the artic silver properly, see articsilver.com for info

I'd put an 80mm in the empty for exhaust, & if you have the tools, cut a 120mm on top for exhaust...it will help release all that heat.:burn:

Ok Jimmy, I think I may be able to relate to your problem somewhat.

I have a Swiftech 462 also, and my ambient is about 22-24C too. But with, or without, the case cover, my full load temps don't go above 40 (I have a lot of airflow through a big case). Since you have a TB 1.33 vs. my TB 1.4, you should be running cooler than me with your case cover off. So, your problem is not high ambient temperature, but rather, something is wrong with your cooling. So here are a few things to check:

1) What fan do you have on your Swifty? I have the Sanyo that came with it, so if you have the same or better move to the next suggestion, otherwise, get a better fan on the Swifty.

2) What thermal compound did you use to mount the Swifty? I used Arctic Silver II. If you used the same, then move to next suggestion, otherwise, if you used a no name, or cheap one, then you got what you paid for.

3) If you have made it this far, then something may be wrong with your installation of the Swifty. This could be due to too much/little compound on the die, or the Swifty is not sitting right on the die. So you may want to take it off, clean it, and reinstall it.

Hope this helps.

One thing to do is to get a accurate temp sensor/digital thermometer to get exact readings. You never know when the thermistors will be accurate. It's imposible to have worse temps than my DOrb3+ with a Swifty so my best guess is the thermistor is off BIG TIME:eek:. My load temps on Prime95;

You have 1 120 in the front and 1 120 blowing on the HSF, but only a dual 60 pulling hot air out? You need to vent the case alittle better. You are putting in 120CFM and pulling out 40CFM (or was that 80?). I would say that you have some back pressure in your case. On top of this, if you have the 120 pushing air into the HSF this could be screwing up the HSF's chi, know what I mean:cool: . These of course are things to think about after you check into the suggestions above of course.

check that you have put the artic silver on peroperly, also try lapping the heatsink and check the the cpu it's self is mounted properly

Yeah, try the 80mm. Even though you're moving air, positive pressure ventilation is counterproductive to dynamic pressure changes.

on your partic ular motherboard, ASUS has put a reader for the Athlon Xps thermal diode, and is probably reporting inaccurate temps as a result, if yoiu read the front page, several people arer havin problems wit this...

I think that I have applied the Arctic Silver properly and that the Swiftech is seated properly on the chip.

The A7V266 motherboard reports exactly the same temperatures as the A7V133 that I previously used with the same setup of everything else!
