Hey Folks,

If you run a BE-2350, could you tell me what temp your chip idles at and how you are cooling it? I have read two conflicting reports, one states 30C and another at 15C.

A 15 °C idle temperature must mean that the computer sits in a room with the AC cranked up to actively chill the room or that it is outside. That measurement is completely irrelevant for real life comparisons. It could also mean 15 °C above ambient temperature but that would mean that the CPUs in the test were 30 - 41 °C over ambient when loaded which seems very high for such low power CPUs.

I would not draw any conclusions from that review.

With an ambient temp of 26C, mine is currently idling at 35C. Cooling is handled by a Ninja in a P180B with 2 Scythe S-Flex fans controlled by a noisemagic controller. The fans spin at ~500rpms and ramp up to 750ish to keep max temps in the upper 40's.

I am using stock AMD C&Q throttling as RMClock performance on demand wasn't stable for me.

This is pretty much a realistic figure for a system set up for minimal noise. Obviously....getting the CPU colder than ambient would be a helluva breakthrough-but I doubt it's something available anytime soon. A rig in a case with more inlet,more fan RPMs,a fan on the HS obviously would lower the temps further----but that's unnesecerry. Even in this rig,a single 500-750 fan would likely still keep temps in a safe zone. For practical purposes however-a pair running at those speeds are very near inaudible and you do get a little more versatility in setting up an airflow pattern.

I'd be curious to see the 2350 compared to the 2300 and to a Brisbane 3600 running at minimal volts. Another thing would be to find out what sort of range is possible with Crystal CPU ID, which if I understand it-can let you get the advantages of both Underclock/undervolt and overclock based on demand. Some motherboards seem to have some form of Dynamic overclock or underclock/volt---but the marketing is focused on the Hot Rod Gamer segment-so the full details hide somewhere in the manual.

On a lot of Mobos there is the ability for the Mobo to control a CPU fan based on CPU load/temps. A 800 rpm Scythe CASE fan can be connected as if its the CPU fan. A second Scythe can be set up to run at a steady 500 rpm. That gets you the As Needed extra RPM without a seperate controller.
The catch is that with some of those mobos-500-800 rpm is below the threshold the mobo handles well.

I'd like to see some sort of shootout between some of the low heat AMD chips with an optimal silencer setup.

Agreed, I definitely prefer to control my fans based on CPU load via Speedfan. Sadly the Biostar board I have only supports PWM fan control and the PWM fans I tried had an audible clicking sound. The noisemagics were my 2nd choice but I am quite pleased with them.

I previously had a x2 3600+ Brisbane in this board but it was paired with a Thermalright Ultra120 extreme cooler. It was more happy with RMClock so I had it undervolted (@0.85V) and idle temps were in the lower 30's while 100% temps (@1.1V) were under 40. I was using the same setup as previously described but with 1 additional fan directly connected to the Thermalright HS.

Keep in mind that the newer BE-2350 chips are still new and aren't correctly identified by some programs so I'm skeptical if the reported core temps are accurate.

15C is almost certainly wrong. My bet is that it was reported by SpeedFan. I have an AMD/ATI 690g board and SpeedFan also reports the same bogus CPU core temperature.

The ondie temperature sensors in the 65nm chips are off. They're known to report wack values like 5c.
