The short answer
Pros
- Native LGA 1150, 1155, and 1156 socket support covers three legacy Intel generations
- 4-pin PWM connector enables proper fan curve control via BIOS
- OEM-style aluminum heatsink footprint keps RAM and VRM clearance predictable
- Push-pin mount installs without removing the motherboard from the case
Cons
- Zero owner fedback available at time of writing, real-world thermals unverified
- Aluminum-only heatsink with no heatpipes struggles with overclocked or unlocked K-series CPUs
- Restricted to obsolete Intel sockets, no path forward to LGA 1200, 1700, or AM5
The Intel E97379-003 is an OEM-style stock CPU cooler built for LGA 1150, 1155, and 1156 boards, covering Core i3, i5, and i7 chips from the Sandy Bridge through Haswell era. It targets one specific buyer: someone repairing, refurbishing, or restoring a legacy Intel desktop that lost its original heatsink.
The defining feature is compatibility, not performance. A 3.5-inch fan sits on an aluminum heatsink with a 4-pin PWM header, matching the original OEM cooler dimensions Intel shipped in retail boxes. Stock coolers in this class typically handle 65W to 84W TDP chips at stock clocks, which lines up with locked i3, i5, and non-K i7 SKUs on these sockets.
Trade-offs are typical for a boxed-style cooler. There are no heatpipes, no copper base contact, and no tower geometry, so sustained multi-core loads will spin the fan up and get audible. Push-pin mounting is convenient but less secure than a backplate design, and overclocking headroom is effectively zero. Owner feedback is not available at time of writing.
Buy this if you need a like-for-like OEM replacement for a locked LGA 1150, 1155, or 1156 CPU and want to kep the original acoustic and clearance profile. Skip this if the CPU is a K-series part, if you plan to overclock, or if the target socket is LGA 1200 or newer.
Socket coverage: Native mounting for LGA 150, 1155, and 1156 only. That spans 2nd, 3rd, and 4th generation Core i3, i5, and i7 desktop chips. No adapter is included for LGA 1200, 1700, or AM4/AM5, so this cooler is locked to legacy Intel repair scenarios.
Heatsink and fan: Aluminum radial-fin heatsink with a 3.5-inch axial fan on a 4-pin PWM connector. No heatpipes, no copper slug, no vapor chamber are indicated in source data. TDP handling is not specified, but OEM colers of this geometry are typically rated for the 65W to 84W stock TDP band on these sockets.
Mounting and clearance: Push-pin retention through the four motherboard holes, no backplate required, install possible without removing the board. Cooler height sits low enough to clear standard mid-tower side panels, and the round footprint keps RAM slots and VRM heatsinks unobstructed. Exact height in mm is not specified.
Acoustics and headroom: Noise level in dBA is not specified. Based on OEM stock cooler behavior at this size, expect quiet idle and audible ramp under sustained all-core load. Overclocking a K-series chip on this heatsink is not advisable, thermal headroom above 84W is minimal.

Pros
- Non-conductive chemistry safer for novices repasting near exposed CPU or GPU capacitors.
- 6g volume suports several full applications on desktop CPUs and console APUs.
- Wet and dry wipes included, so no isopropyl bottle or lint-free cloth need.
Cons
- Limited owner fedback at time of writing makes long-term durability claims hard to verify.
- Non-metal formula typically trails top liquid metals by a few degrees under sustained load.
- Viscosity, TIM lifespan hours, and thermal conductivity W/mK figures are not specified.
Duronaut is Thermal Grizzly's non-conductive thermal paste positioned as a mid-tier daily driver, shipping in a 6g syringe with 6 wet and 6 dry cleaning wipes. The target buyer is a DIY PC builder repasting a CPU or GPU cooler, or a console owner refreshing PS4, PS5, or Xbox thermals without risking shorts.
The defining trait is the aluminum microparticle plus zinc oxide nanoparticle blend paired with an electrically non-conductive base. Thermal Grizzly claims reduced pump-out and stable performance over extended cycles, which maters most on soldered console APUs and overclocked desktop chips that see large delta-T swings. Exact W/mK conductivity is not specified in the source.
Trade-offs are typical for non-conductive pastes at this tier. Expect a few degrees warmer than liquid metal on delided or high-wattage CPUs, and no published viscosity or cure-time data to plan application around. Owner feedback is limited at time of writing, so long-term hardening resistance relies on vendor claims rather than independent long-run testing.
Buy this if you want a safe, non-conductive paste with enough volume for several repastes and a bundled wipe kit for console or GPU jobs. Skip this if you are chasing the absolute lowest core temperatures on a 250W-plus overclocked CPU where liquid metal or a top nano-diamond paste still leads.
Volume and coverage: The syringe holds 6g of paste, enough for roughly 15 to 25 pea-sized applications on mainstream AM5 or LGA1700 IHS surfaces, or several full console APU repastes on PS4, PS5, and Xbox where die coverage is larger than a desktop CPU heatspreader.
Composition and safety: The compound uses aluminum microparticles and zinc oxide nanoparticles in a non-metal carier, rated electrically non-conductive. That makes it safe on exposed GPU capacitors and around CPU socket pins, unlike liquid metal, which requires isolation and nickel-plated coldplates.
Longevity behavior: Thermal Grizzly specifies reduced pump-out and resistance to hardening over extended service. Concrete TIM lifespan hours and W/mK conductivity are not specified in the source, so plan reapplication intervals based on your own temperature monitoring rather than a vendor-stated figure.
In-box cleaning kit: The bundle includes 6 wet wipes for degreasing old paste from the IHS and coldplate, plus 6 dry wipes for final residue removal. Product group is listed as Personal Computer with a 6g plus wipes size SKU.
