In all probability your suction apparatus fan. It is a little fan that pulls air from the lodge through the little grille neighboring the atmosphere controls.
It can get messed up in a few ways: 1) It can amass dust, hair, and so on that causes it to buzz. If so you can either utilize some packed air and blow through the little grille or utilize a shop vac and suck through the grille and perhaps free it up.
The other way the fan can buzz is if the orientation begin to destroy. To settle this, you need to expel the fan. This includes evacuating the middle console, ashtray gathering, stereo and atmosphere control unit. You then need to expel the fan and somewhat dismantle it. I think the fan is made by Denso. It is about $250 from the merchant.
On a NSX gathering, somebody did a DIY on the best way to alter the fan. You essentially need to change the hub play out of the direction. The entire technique is genuinely included however truly clear on the off chance that you have a few pictures and an administration manual. Get on the NSX Prime Forum and do a pursuit on "Suction apparatus Fan".
I at long last did mine and it is much calmer (however not noiseless). Figure about a large portion of a day to do the entire thing. Good fortunes.
