Phobya 120mm Radiator Gasket - 5mm Thick Self-Adhesive Fan Seal

About This Product

So if you're into PC water cooling and want to squeeze every bit of performance out of your system, this Phobya radiator gasket is one of those simple upgrades that actually makes a noticeable difference. It's a 5mm thick foam gasket that you stick between your fan and radiator to seal up those gaps where air normally leaks through. See, when your fan isn't perfectly flush against the radiator, you lose airflow efficiency - this gasket solves that problem completely. The self-adhesive backing makes installation super easy - just peel and stick to your radiator, then mount your fan normally. It compresses down to less than 1mm when you tighten everything up, creating a perfect seal that forces all the air through the radiator fins instead of leaking out the sides. I've used these on several builds and they typically drop temps by a few degrees, which is pretty impressive for such a simple and affordable mod. They're pre-cut to exactly fit 120mm fans, so no trimming or messing around required. If you're chasing better cooling performance or just want your water cooling setup to run as efficiently as possible, these gaskets are totally worth the small investment.
