Unless one can quantify such a statement with cold hard facts, and not heresay, or 'fanboy' opinions etc, we should refrain from doing so.

Where is the proof that Noctua/Silverstone spend more time in R & D than Scythe do?


The only way one can make such a statement and have it stand up to scrutiny, is by providing inside R & D info gleaned from the various companies Labs-the rest is all Marketing, sure the stats may be nearly correct (all company's embellish performance stats), but its all bells and whistles when dealing with the various high end models, there is so little to differentiate between them when it comes to performance.

And using the retort 'Everyone knows this' isnt a viable reply, its just words.


Some companies also choose not to advertise as heavily as others.

Retailers and reviewers are very fickle when it comes to products-pay them enough and they will try to convince you that eating handfuls of plutonium is great for your health biggrin.gif

Just recently, a very well known PC gear reviewer, said that the new Corsair fans were equal if not better than the Noctuas, and that he will be using Corsair from now on rolleyes.gif

We are all entitled to our opinions, but to say that x does more research than y without solid facts is tantamount to non information imo wink.gif

Excuse the OT


PS-just some info for those interested in Fans and their performance

What is stated above. thumb.gif

Too bad there isn't a much bigger list of fans. None of the new fans are listed there and many old ones are missing.

if you understand physics, you'll understand how wrong that statement is biggrin.gif the fan blades on a GT required more research and has a higher technical hurdle to overcome then any computer fan available on the market. the reason is the fan blades themselves are MUCH longer on the GT then the typical design. essentially they fit the fan blades of a 140mm fan inside a 120mm frame. the curved nature of the fan blades themselves gives a greater technical challenge (in terms of balancing and warping during operation) then any other fan blade assembly of its size. the fan blade design of the GT gives it the unique properties that people are looking for and no other fan blade can accomplish.

the Silverstone AP1x1 fans are no different then any other fan. their difference is the frame of the fan and the physics behind the built in grill of the frame is well known and does not require additional R&D. and it's not harder to build since the frames are just molded plastic.

there may be some additional R&D into noctua fans but their primary advantage is in their bearing design. balancing and stability wise the noctua fans are no different then any other fan in the world in terms of technical challenge to overcome.

the GT is superior to most fans precisely because they are technically the most difficult fans to make and requires a great amount of R&D to make them work.

^nicely said, i always thought my AP-15s were the best fans, if only they had PWM they would be perfect.

I agree 100% mate-ive been looking,

but it seems that to get stats and info for comparison, one has to take each model on its own, look up the various reviews, note the stats etc, and do the same for all the other ones that may be on your 'radar'-then its compare and contrast wink.gif

Unless someone else knows of an alternative.............

To put things back on topic, the reason i came across this thread is because i was looking for info on painting my fans blades for a new job i am about to embark on-having read many threads, articles etc-i have come full circle, and will endorse Sean W when it comes to what he said about actual painting of the blades-ie thin coats (id do no more than 2 if possible)-preparation of the blades is also of paramount importance.

painting the fan blade is not rocket science. it's just a matter of a steady hand and patience. you have to do multi coat and each coat has to be VERY light and even coats. if you spray too much, the paint clump up due to gravity while you wait for it to dry and that throws off the balance. I don't recommend anyone spray paint their fans, but it's not impossible if you are patient and keep the fan blades in a dust free box while waiting for it to dry. can be a multi-day job if you want to do it right tho. the good news is the bearing on the fan will compensate for very slight imperfections.

Thread Starter 
Was not expecting more replies to this thread but thank you for the extra information.

I have quite a bit experience painting from doing slot cars / model rockets when I was younger, I will be painting 8 GT AP-15s this summer for my 480 monsta install.
