Review: Excellent for the price - Specs before cooler: CPU: 5600g GPU: EVGA 3060ti XC w/ 3080 fans Case: Be Quiet! Pure Base 500dx Intake: 2x 140mm Pure Wings 2 Exhaust: 1x 140mm Pure Wings 2 (rear exit), 1x 92mm random fan below GPU (GPU only curve) My 3060ti is my main (gaming) monitor, and I use the integrated graphics for my second monitor (browsers, file explorer, office programs, etc). I monitor temps or have a browser open while gaming on occasion. With the stock cooler my 5600G would approach semi alarming temps when playing a demanding game. High 70s maybe low 80s. Now I stay in high 60s, occasionally reaching 70. This is more than just the cooler, though. Getting this cooler I knew the fan wasn't going to be as quiet as I wanted it to be. Plus it wouldn't match. I bought a Be Quiet! Pure Wings 3 120mm to clip onto it instead. Percentage to percentage, this fan is quieter. It's also been designed for airflow and to push through radiators and coolers. I used the included Thermalright fan as a second exhaust fan (top exit). Since it's louder I gave it its own curve. At idle and doing office work the CPU temps are fine with just one exhaust. Because of this I set this fan to stay at 30% until there is some serious load being put on either the CPU or GPU. This keeps the temps right where I want them. I do believe having this fan there also helped my GPU temps a tad. In conclusion- for the price it's perfect! Very effective for a budget office setup. With my Pure Wings 3 addition, this setup isn't only cooler than the stock Wraith, it's quieter too. In the video I compare my fan of choice to the one that comes in this kit. The phone mic amplifies the volume a little bit, both are quieter in person. With that being said, the difference is still noticeable. *Thought to consider though, one is further in the case than the other. The "stock" fan I used as exhaust could potentially be muffled a small amount by the case.
Review: Thermalright keeps getting it right! - Thermalright has yet to disappoint me. The price is fantastic and quality is on part with coolers 25% more expensive. I have purchased about 10 Thermalright coolers over the past few years and they always perform very well. I just hope Thermalright doesn't raise their prices to keep the value.

### ⭐⭐⭐⭐⭐ Good CPU fan
*by T***A on June 4, 2024*

Can't really talk about the noise level of this fan since I have an old noisy GPU installed in the system, though I can say it's no louder than that is (very low bar, lol). Works fine, install was as easy as it gets with CPU fans. I used the included thermal paste and haven't had any problems so far, though I'll admit I haven't really pushed my CPU hard. Hooked up the light to the hub controlling the case fans and everything works in sync without issue.
