Review on 🌙 Noctua NH-D14: Deluxe CPU Cooler with Dual NF-P14 PWM and NF-P12 PWM Fans (Brown) by Pradeep Dhimal

I bought this to replace the stock fan on my 4790k. I had some serious temperature issues when using TurboBoost (up to 4.4GHz) and maxing out the processor at almost 100% at 1,260V. I reached temperatures of up to 95°C, which I immediately stopped charging to avoid serious damage. Needless to say, a standard cooler is NOT a practical solution for operating at such high frequencies and voltages. I disabled TurboBoost in the BIOS, which limits the default CPU clock speed to 4.0 but also lowers the max voltage to around 1.15. This reduction in voltage lowers the temperature. But why unlock a powerful processor that I have to endure with a stock cooler? Enter NH-D14. The installation wasn't "easy", but it wasn't difficult either. Instructions are provided in separate books for AMD/Intel. As instructed, I removed the motherboard, installed the backplate (fairly easy), and installed new radiator brackets on the opposite side. This will give you mockups for the final product in the guide. I chose to place the intake on the side closest to the drive bays and the exhaust on the opposite side so that it faces the case's rear fan (both fans move air in the same direction, away from the sinks). I believe this will be the most efficient way to install in 90% of applications. The hardest part of installing this receiver is finding a place for it. I DO NOT RECOMMEND THIS REFRIGERATOR IF YOU ARE USING SLIGHTLY LESS THAN ATX MOTHERBOARD AND MID-ATX CASES. I'm using a mid-size standard ATX board and a standard ATX board. I had plenty of room to install everything, but the tall heatsinks on my Corsair Vengeance RAM caused an issue and I will be replacing the memory rather than removing the heatsinks voiding my warranty. One last piece of advice: don't try to install a cooler while the board is out of the case. I haven't tried this, but I highly doubt it will work. Getting your hands down the side streets of the body is harder, but best of all. The fans are both removable and vertically adjustable thanks to neat brackets. You can even flip them instead of the sink if you need a different airflow configuration. If for some reason you prefer to have only one fan (or can only fit one), you can simply remove one and use it as a 140mm case fan. You can also remove and use your own fans if you don't like the look, but I imagine they're quieter than most fans you get and you might have issues with the mounting system. . Let's get to the fun stuff: My temperature has SIGNIFICANTLY improved. My pre-install idle temp was around 35C (with Turbo and Speedstep on). After installation, the idle temperature often dropped to 22°C (below my room temperature) but fluctuated between 22-26°C. As mentioned, under load with a stock cooler and the above settings, the temperature reached 95°C. With a new cooler installed I can keep 4.4GHz at 100% load forever and the temps never go above 70 and are usually between 60-65C. All of these tests were conducted in a home with an ambient temperature of 22.2°C (72°F). See photos for my proof! This is not a paid review (see verified) but an honest opinion on this product. I can't imagine there's anything better. I just wanted to let everyone know how great this cooler is. If this review was helpful to you, please click "Yes" below!
