*SIMPLE* process monitor - for peaks?

Does anyone know of a _simple_ process monitor, ideally with an
adjustable threshold, that will show when anything (other than "System
Idle Process") is using more than x% of CPU, _and show what it is_
(ideally with slight delay/prolongation)?

I have (SysInternals) Process Explorer, but that - and even just Task
Manager - are somewhat tedious to use in this way - especially for
relatively (second or two) short-term peaks. [Shorter than that wouldn't
bother me.] Ideally, I'm thinking of something with a _small_ window,
that normally shows nothing (or some "all is well" indication), but
shows the _name_ of the process when something goes above - I don't
know, hence me wanting it to be adjustable, but say 10%? - CPU for more
than a second or two.

So when I'm doing relatively little, and the fan suddenly ramps up and
then down again, I'm not left wondering "what caused that?"

(I've thought of just using Task Manager [in CPU-sorted mode], and
shrinking its window vertically, but that wouldn't really be
satisfactory - not least because [AFAIK] you can't have it _not_ display
System Idle Process, which would usually be at the top of the list.)

"If even one person" arguments allow the perfect to become the enemy of the
good, and thus they tend to cause more harm than good.
