ASSASSIN IVTHE “AIR” APPARENT
The newest addition to the ASSASSIN series claims the air-cooling crown in both cooling capacity and ultra-quiet operation.
BEAUTY IN SIMPLICITY
The elegant design of the ASSASSIN IV is not just visually pleasing; it also leads to optimal air flow and maximum compatibility.
IN SILENT OR EXTREME MODE, THE ASSASSIN IV REIGNS SUPREME
With a simple slide of a switch, the ASSASSIN IV can morph from a whisper-quiet cooler when low noise is of the utmost importance to an unrestricted cooling powerhouse when peak performance is all that matters.
LET IT SHINE!
The ASSASSIN IV's case is clean, sleek, and helps channel air through the fin towers, while the relocatable 120mm fan provides unobstructed clearance for high-profile RGB RAM.
RAM Clearance
Intel LGA1700/1200/115X: Unobstructed
Intel LGA20XX: 63mm
AMD: AM4/AM5: Unobstructed
BE COOL, BE CALM
A key factor in the ASSASSIN IV's extremely silent operation is the use of three-phase, six-stage fan motors with low voltage and power consumption. DeepCool is so confident in our new design that the ASSASSIN IV comes with 6 years of limited warranty coverage!
EXCEPTIONAL BY DESIGN
Featuring seven heat pipes that deliver improved heat transfer through two fin-array heat sink towers for high performance efficiency. The included DM9 thermal paste meets the rigorous standards used in industrial applications.
STREAMLINED INSTALLATION
Installing larger air coolers can be difficult and is a prime reason the hardware and installation was designed to be extremely user friendly. Even the magnetic top fan cover was crafted with ease of installation in mind.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.
