By the way a generaly question:
Why all want to cooling the Pi? I use applications with high performance for Video rendering etc. I never needed a activ cooling? I also operated Pi´s in small cases without heating problems… And OP, opencpn and signalk didn´t need high performance of the pi… ???
For the Cooling I use the alu Flirc case. The alu case has a pillar connected with a thermal pad to the processor. The whole case act as a cooling system. No need to a use a fan. It has a plastic lid so that the Wifi can still be used.

My Pi´s toggle around 55-63°C with OP, signalk and opencpn in a case at ambiente temp of ca 24°C….
The pi clocks down at 85°C. I think all below 75-80°C is ok... You can see this by typing vcgencmd measure_temp
With the alu Flirc case the temperature of the RPI4 processor is around 35 o C. And the case handwarm.

The flirc case is excellent as others have said but if you're really worried about heat as I was I removed the top plastic plate and added some heatsinks. I use thermal compound between the heatsink and the case.

I procured the above case with 2 fans on ebay for less than 10 € ! - without it, but with a large passive radiator, I could monitor up to 65°C when using intensely OCPN in an ambiant of 20 °c ... - with the above case, without powering the fans, : 55°C - with above case when powering the fan in serial, 45°C, (40°C when idle) - The performance can be further improved by connecting the fans in parallel, but it is not needed... Why connect the fan in serial : each fan will pe powered in 2,5 V, which means more or less half speed and 1/4 of noise level ! I need to bring the case close to my ear to perceive it ! And that's not due to my age ! OK, I have to say that, for 1st start, I had to help the fan to turn with a gentle finger push, but that occurred once only, then they start to turn when the power is applied ... I think I found the proper case for my on board installation : VALIDATED
