Yes. Raising the temperature also makes HDDs last longer (Google FAST’07). Cold aisle inlet temperatures of 35C are not impractical.
Saying that CPUs "throttle" with inlet temps as low as 35C is a bit simplistic. Typical server CPUs have t(case) of about 70C, so you just need to run the numbers: θCA, package power, airflow, and inlet temp → steady state thermal solution.
