I’m not sure if I should increase the airflow over my Cascade. It’s between 40-45 degrees Celsius with the ambient air temperature going to 35. I put some whisper fans on the system and am using a 30 degree setpoint.
Any thoughts or suggestions

I really wouldn’t bother with fans or improved cooling unless your Cascade case temperature was over 50C on a regular basis. Internal components do not run more than a couple of degrees C over case temperature.
Good to know, I will turn them off and see what the case temp climbs to, or leave them as they are installed and working well 
@Peter.Bomberg , are the 3 units of your Cascade stacked up together? An ambient room temperature of 35 deg celcius sounds very high to be comfortable in your room. Where do you measure the ambient temperature? Is it 35 deg celcius just above the Cascade with the top casing of the Cascade meauring 40-45 deg celcius?
@Easyglider they are stacked and I am measuring between the powerbase and the director, the ambient room is 18-20, the new probe is surface mounted to the powerbase.

@Peter.Bomberg , May I know what temperature probe you are using? The top case temperature of my Cascade Powerbase which is on a separate platform is warm, while the top case temperature on the stacked DD/DAC is also warm to the touch. I have not measured the temperatures of the casings using a temperature probe. My room ambient temperature is 27-29 deg celcius without air conditioning turned on. The top of the Powerbase is probably close to 50 deg celcius.
Just for a comparison…
I am using an infrared temp probe.
My ambient temp is about 24C, which is 8C below the max the manual specifies. No added fan, just natural convection.
Top of my DD is 32C
Top of the Cascade DAC is 39C
Top of the M500 is 39C
My DD is separated from the Cascade DAC which is stacked over the Power Base. The Cascade has about a foot space above it. The DD had eight feet above it.

The internal components in our products with the greatest temperature induced aging are the electrolytic capacitors used for bulk filtering in the power circuitry. Using the most conservative estimates of our products long life capacitors you should expect a fifty+ year lifespan for product case temps below 50C (-20% of rated capacity). Once you reach 60C (continuous) product case temperature the expected capacitor lifespan drops to only about 25 years. I wouldn’t run any of our products with a case temperature over 60C and would definitely suggest an effort to improve ventilation, decrease ambient temperature or turn off the equipment if it ran above 60C. At around 65C most of our products will automatically shut off.

@Dan , i remembered last time all 3 chassis of your Cascade were stacked together. Now you have separated the DD from the DAC/Powerbase? Is that to manage the temperatures of the Cascade stack?
Hi @Easyglider
It was for aesthetics. The DD is on top of my wide BDI cabinet . The DAC and Powerbase are inside the BDI. Once everything is finished the DAC and Powerbase will be behind a cabinet door. I wanted to make sure the DD display is visible.
