Many companies have attempted to make a passive cooler work. Some have included the hardware to mount a fan and some have not. The latter category products have pretty much all failed to impress anyone not running a specialty CPU that uses low voltage, i.e. low performance, underclocked from the factory.
The other category is passive CPU coolers that have the option or even require an aftermarket fan; they've always done pretty well. The end user can chose what type of cooling performance to acoustic noise ratio they prefer. The downside of this is of course cost as you have to calculate the fan and cooler cost. In today's test we used a 40 Dollar cooler with a 16 Dollar fan making the total just under 60 Dollars total.
Looking at our two performance charts there are many other coolers that I would personally choose over the ASUS Triton 75 in this price range, but then again these coolers do not match the Triton 75 in terms of customization for the end user.
