Yeah... that fan screams man

... i think the design and layout of the cooling system was really because of its intended use... stuck inside a hot blade server running for countless
hours allowing them to get a little warm... I am guessing since we have them out of those hot, cramped spaces they are 'use to', they'll run much cooler... so if you have a fan that will be
quieter and can still move a good volume of air through PS... it should be fine... run some tests and make some comparisons with temps...
