this is the reason

you could run a cooperation with companies that have larger capacities (since AC heatsinks aren't that different from other ones)

that would eat away much of the already very small profit margin

Ooooh yeah got one finally 28 C (according to the BIOS) Idle, 35 C Load

compared to 30 Idle and 36 Load with the Freezer 64

this is interesting.. could this new AMD heatsink be made by Coolermaster?

Quote:

When FX-57 was released it was shipped solely with a PIB cooler developed by AVC. Since launch, AMD have also sought out another model to ship along with FX-57 and their other ~100W CPUs. That other model is what'll also ship with FX-60. Manufactured by Coolermaster and called CMHK8-8I22A-A2, let's have a closer look at it.

Compared to the first FX-57 PIB cooler, the Coolermaster has all four heatpipes aligned on one side of the cooler, rather than two per side. The cooler, including heatpipes, is also around 5mm shorter in major width, although it retains the same 62mm height. The fan is an 80x20mm Delta, up from 70x15mm on the first FX-57 PIB example, allowing the fan to move a larger air volume at the same fan speed, or the same volume at reduced speed.

Presumably the differing cooler design and fan are primarily to achieve the latter, making this PIB cooler even quieter under the same conditions as the AVC. It appears, although we can't confirm, that the cooler also comes supplied with a Dow Corning thermal material, whereas the AVC cooler is equipped with a Shin-Etsu thermal pad. The heatpipes are outwardly identical with a 5mm width and equivalent length, and we're told they each have a 30W capacity, making the CMHK8-8I22A-A2 a 120W capacity device.

Finally got a chance to oc my system. With absolutely no fuss i got it at 2.4GHz using the stock cooler and at stock voltage.
Primed it for 3 hours this afternoon. It got up to 48C, but no higher. Idling now in the evening at 34C.
What do you guys think, good temps?

Sidney · 5th March 2006, 08:22

I'd say it is an acceptable temp should your room temp is ~20-22°C. Asking people whether an overclock CPU temp with low 30°C idle and high 40°C is like telling people your car can do 60 mph in 8 seconds with a question to follow. Is my car fast enought?

Assuming you have the Opteron 165 which is rated a 110 watts, and @2.4 Ghz assuming at stock vcore is ~130 Watts -

Room temp is 20°C; Load temp 48°C = 28°C rise above ambient
C/W = 28/130 = 0.215

0.215 C/W heatsink is considered a high performance not too long ago. The actual C/W would be lower because your case temp will certainly be higher than 20°C room temp.

I am sure if I tell you that the temp is great; you'll be overjoyed, otherwise you will be scratching your head

So, why don't you tell me, if it is a good temp

The other fellow is overjoyed with 35°C load temp using another HSF. Assuming he did not overclock and the same room temp, that is 15°C above ambient.

C/W= 15/110 = 0.136

Now, if the heatsink manufacturer lists the specs of 0.136 C/W which is better than most high price water cooling; everyone will get one, won't they? 35°C is hell a lot better than your 48°C. The question becomes if the temp is correct or not.
---------------------------------------------------------------------------

They key here is that your system is stable; and temp does not exceed spec of 60°C and the CPU fan does not have to run at full speed at loud noise. The Stock Heatsink Fan is doing more than the job it was designed, at overclocked speed.

I just got this HSF and was wondering how to get the fan to run at 5,200 RPM all the time. I want to be able to control the RPMs of the fan from within windows. My fan doesn't really increase RPMs even when my chip gets hot. I figure the temp sensor on the fan is dependant on my case temperature which never gets that hot. I have heard of people using a small wire to short circuit the temp sensor but I don't know how to do that and am worried about killing the fan.

Sidney · 5th March 2006, 14:54

Simply tie a bare wire around the two leads of the green color heat sensing resistor on the back of the fan. You will have to unmount the fan from the heatsink. My suggestion will be to get a regular 80mm fan rather than fooling around with the reisitor if you are not sure.

At 5,200 rpm I find it too loud for anyone's liking; and it does not reduce temp much. I found the best noise and temp of my setup be around 4,400 rpm max.

lazyman, thanks for the input. Im sure that my cpu idles higher at 2.4GHz now due to the higher system temps i see due to SLI. I took one of my cards out and saw my temps drop from about 34-35C to 32C. My card temps dropped from 50C to 40C! Needless to say, the bottom card is cooking the top one.
I am real happy with my system running at 2.4GHz at stock voltage. 2.6GHz is next.
