AI Verdict
This is a $26 drop-in replacement for noisy stock coolers that easily handles 65W CPUs like the Ryzen 5600X while staying dead silent and clearing all your RAM slots.
This cooler is strictly designed for 65W-95W CPUs running at stock speeds in compact cases. If you push 150W through it with an aggressive overclock, your CPU will hit 97°C and throttle. It excels purely as a cheap, silent alternative to the jet-engine stock coolers.
If your CPU draws more than 130W TDP, upgrade to a dual-tower cooler with a 120mm fan.

Pros
- Drops Ryzen 5600X temperatures by 20°C compared to the stock AMD Wraith Stealth cooler.
- Max noise output is just 25.4 dB(A) at a full 2000 RPM, making it virtually inaudible inside a case.
- At 135mm tall and 82mm deep, it guarantees 100% RAM clearance even with tall memory sticks.
- AMD installation uses the stock motherboard retention brackets, meaning you don't have to remove the backplate.
- Comes with thermal paste pre-applied to the copper base.
Cons
- Intel installation relies on cheap plastic push-pins instead of a secure screw-in backplate.
- Caps out at 130W TDP, meaning it will thermal throttle on high-end chips like the Core i7-10700K under heavy load.
- Packaging is flimsy, leading to multiple reports of bent aluminum fins upon delivery.
- The 92mm fan uses wire clips that can be frustrating to snap onto the heatsink in tight cases.
Dimension Scores
Handles 65W chips easily with a 20°C drop vs stock, but chokes on anything near its 130W limit.
The 92mm Pure Wings 2 fan maxes out at 25.4 dB(A), making it nearly silent even at 2000 RPM.
The brushed aluminum top plate looks premium, but the Intel push-pins feel cheap and fragile.
The 4-pin PWM cable is sleeved in black and easily tucks behind the motherboard tray.
Best For
- Upgrading from a loud stock AMD Wraith or Intel Laminar cooler on a strict budget.
- Mini-ITX or Micro-ATX builds where standard 155mm tower coolers won't fit against the glass panel.
- Locked 65W CPUs like the Ryzen 5 7600 or Core i5-12400F used for gaming or office work.
Not Recommended For
- Overclocking unlocked K-series Intel chips or Ryzen 7/9 processors.
- Aesthetics-focused builds, since there is no RGB and the heatpipes are exposed copper at the base.
Watch Out For
- Intel mounting uses plastic push-pins instead of screws — if you press too hard at an angle, they will bend or snap.
- The thermal paste is pre-applied with no plastic cover, so if the box gets squished in transit, the paste smears everywhere.
- The AMD mounting clips require a lot of downward force to latch onto the stock motherboard brackets, which feels terrifying the first time you do it.
- The 92mm fan uses wire clips that are frustrating to snap onto the heatsink in tight cases.

What Buyers Say
Intel users despise the plastic push-pin mounting system, while AMD users praise the two-minute installation using factory motherboard brackets. The acoustic upgrade over stock coolers is massive. Many Ryzen 5600X owners report 20°C temperature drops under heavy load. The 135mm height saves older, narrower PC cases from side-panel clearance issues. Pre-applied thermal paste frequently smears against the packaging during transit due to a lack of a protective plastic cover.
“Threw my screaming AMD stock cooler in the trash, slapped this on my 5600x, and dropped 20 degrees instantly—just wish the mounting clips didn't feel like they were going to snap my motherboard in half.”
Common Praise
- Drops Ryzen 5 3600/5600X temperatures by 15-20°C compared to the Wraith Spire.
- The 92mm fan is completely inaudible over case fans, even during Cinebench runs.
- Clears tall RGB RAM sticks like Corsair Vengeance without needing to offset the fan.
- Fits perfectly in narrow 3U server chassis and older Dell Optiplex cases due to the 135mm height.
Common Complaints
- Intel push-pins are fragile and pop out if the case is bumped hard.
- The AMD tension clips require an uncomfortable amount of force to lock down.
- Box arrives crushed frequently, leading to bent aluminum fins on the outer edges.
- Pre-applied thermal paste gets smeared on the plastic packaging during shipping.
Ownership Tips
- The fan curve needs to be adjusted in the BIOS; otherwise, it ramps up aggressively at 60°C.
- Dust buildup is minimal because the fin spacing is relatively wide.
- If you ever need to repaste, cleaning the pre-applied paste off the grooved direct-touch heatpipes takes extra rubbing alcohol.
Frequently Asked Questions
Does this come with thermal paste?
Yes, thermal paste is pre-applied to the bottom of the heatsink. You don't need to buy a separate tube unless you mess up the first installation.
Will this fit the new AM5 socket for Ryzen 7000?
Yes, it uses the exact same clip-on mounting mechanism as AM4. It snaps right onto AM5 motherboards without extra brackets.
Does it include the LGA 1700 bracket for Intel 12th/13th gen?
Recent batches include the LGA 1700 push-pins in the box. If you get old stock, you must request a free mounting kit from be quiet! support.
Does this block the first RAM slot?
No. The heatsink is only 82mm deep with the fan attached. It leaves all four RAM slots completely unobstructed.
Can I add a second fan for push-pull?
No. The box only includes two wire fan clips, and the heatsink geometry is optimized for a single 92mm fan.
Buying Guide
You are buying this to fix a noise problem, not to set overclocking records. The 130W TDP rating is technically true, but pushing that much heat will spin the 92mm fan to its 2000 RPM max, defeating the purpose of buying a 'be quiet!' product. Check your CPU's actual power draw under load. If it stays under 90W, this cooler will keep it chilly and silent. If you are on an Intel motherboard, be prepared to wrestle with plastic push-pins.
130W TDP (Thermal Design Power)
Think of this as the cooler's maximum heat capacity. If your CPU generates more than 130 watts of heat, this cooler will get overwhelmed and your PC will slow itself down to prevent melting.
135mm Height
This is the distance from your CPU to the case's side panel. Standard coolers are 155mm tall and block the glass on smaller cases; this 135mm cooler fits almost anywhere.
92mm PWM Fan
PWM means your motherboard can control the fan speed automatically. It spins slowly when you're browsing the web and speeds up when you're gaming.
Alternatives
If you have a CPU that draws more than 100W or you absolutely despise plastic push-pins, look for a 120mm tower cooler with a dedicated metal screw-in backplate.
