When ciarlatano was doing all his AIO/CLC & air cooler testing I did some charts with his data.
Air cooler having slightly lower intake air temp instead of being warmer is strange. Normally when testing in a case, air cooler intake temps a significantly higher than radiator. But even with that anomaly there is a 6.8-8.8c difference in intake air temp compared to room. The fact that only one air cooler was used begs the queston "waht would other air cooler intake temps be?" Especially coolers that are not same design as D15 (twin tower).
How can anyone can think testing coolers in a case is 'real world testing'?
Especially when they monitor room ambient and not cooler intake air temp. Even ciarlatano wiht his well ventilated case ran 6.8-8.8c warmer intake temps. Testing in a case using room ambient only show how coolers perform in the 'real world' of the tester's system. Testers are not comparing how the coolers perform against each other, but instead are comparing how their system performs with different coolers in it .. and because very few (if any) have the same system as tester, the results are not applicable to our needs.
At least to me they are not.
I don't want to know how the testers system performs with different coolers.
I want to know how the cooler compare to each other with no other variables involved. That way if i have cooler 'X' that give 5c better CPU temps than my cooler 'Y' and when I install cooler 'X' in my system and get the same temps i had before, I know my case airflow has changed and is cooler 'X' is ingesting 5c warmer air than cooler 'Y' was.
It is only common sense to remove as many variables as possible from the test procedure.
Using cooler intake air temp instead of room ambient eliminates variables.
Would you look at a thermometer in the bedroom and assume that reading is the temp in other rooms? Yes, it may be .. but there is also a very good chance the other rooms are warmer or cooler.
