Prime Day PC maintenance tools: screwdrivers, cleaners and thermal paste on sale

Assembling a PC involves careful planning and component selection, but the work doesn't end once the build is complete. Proper maintenance requires the right tools—and many of those tools are currently discounted during Amazon's Prime Day sale. Whether you're a first-time builder or an experienced technician, having quality equipment on hand prevents frustration and protects your investment.

Precision Kits

All the gear, and lots of ideas?

Starting with the right toolkit makes a significant difference. Comprehensive kits designed for PC maintenance come packaged in sturdy cases and include every bit and driver you're likely to need. Multiple Tom's Hardware staff members rely on Hoto screwdrivers for servicing PCs and components like motherboards, cases, and fans.

• NEX O1 PRO 3.6V Screwdriver Set: was $49.99 now $28.48 — Wireless screwdriver with three torque settings, USB-C charging, and a complete bit collection in a sturdy box.
• HOTO SNAPBLOQ S-A01 3.7V Electric Screwdriver: was $99.99 now $79.99 — Includes 56 bits (Slotted, Phillips, Hexagon, Hexagon Security, Torx, Torx Security, Pentalobe, Standoff, Y-Shaped, Tri-Wing, Triangle, Square, U-Shaped, JIS, SIM Card Needle), three torque settings, integrated light, and USB-C charging.
• 155 Piece Electronics Toolkit: was $59.99 now $37.99 — Precision screwdriver with 140 different bits plus spudgers, pry tools, and a suction cup for first-time and experienced builders.

Hex wrenches, also called Allen wrenches, deserve a place in any toolkit despite being frequently overlooked. Budget options often use soft materials that strip easily or lack the strength needed for precision work. German-made Wera hex keys offer durability and design features that justify the investment.

• 950/9 Hex-Plus Set: was $61.23 now $40.67 — Long arm, ball-headed hex keys from Wera covering metric sizes 1.5 to 10mm with precision engineering and strength.

Everyone should own these great electric screwdrivers!

At least five Tom's Hardware editors own a Hoto screwdriver. Electric screwdrivers simplify the repetitive work of building and maintaining systems. The Hoto Pixel Drive features a chunky, rubberized chassis that resists slipping, a twist power ring with three torque levels, and a push-button forward/reverse mechanism. An LED light ring and display showing power output and remaining battery make the tool practical for both PC work and household projects.

• Si Pro Electric Screwdriver: was $49.97 now $39.99 — Fanttik S1 Pro with 16 S2 steel bits, 3 torque settings (1.5 to 4.2N.m), storage case, USB-C charging cable, and manual.
• PixelDrive Electric Screwdriver: was $79.99 now $59.99 — Latest Hoto model, nearly a year old, discounted 25% from MSRP.
• 25-in-1 Mini Electric Screwdriver: was $39.99 now $29.98 — Compact option with all necessary bits for office, workshop, and portable use, 25% off MSRP.

Screw Kits

Don't screw up your next PC build!

Builders often find themselves searching for spare standoffs or screws to secure motherboards and components. Rather than cannibalizing other systems, purchasing a comprehensive screw kit costs less than $10 and eliminates future shortages.

• Hard drive screws
• Motherboard screws
• Chassis fan screws
• SSD mounting screws
• Insulation gaskets
• High-strength chassis screws (for GPUs)
• M.2 screws
• Flat Phillips screws
• Chassis hand twist screws

• 502-Piece Computer Screw Kit: was $12.99 now $9.99 — Contains 15 different types of screws, stand-offs, and gaskets for securing all PC components.

A similar kit purchased years ago has proven invaluable for anyone working regularly with motherboards and system components. For under $10, it's a practical addition to any toolkit.

Flashlights

Quality lighting is essential when working inside a PC case. A good flashlight illuminates dark spaces, helps identify obstacles, and makes detailed work easier.

• EG0770 Recharable Flashlight: was $28.79 now $16.14 — Outputs up to 100,000 lux with 5-15 hour runtime, five modes (high-middle-low-strobe-SOS), USB-C charging, carrying case and charger cable included.
• E7 Rechargeable Mini Flashlight: was $29.99 now $22.78 — Wuben model with USB Type-C charging, six brightness modes, and magnetic base for hands-free positioning.

Air dusters and cleaners

Clean the filth from your PC!

Electric air blowers offer a reusable alternative to single-use compressed air cans for removing dust from fans, filters, and keyboard crevices. The Wolfbox MegaFlow 100 delivers substantial cleaning power with 150,000 RPM and air velocity reaching 45 meters per second.

This battery-powered blower charges via USB Type-C in 2.5 hours and runs for up to 100 minutes on the lowest setting. The compact design weighs only 0.66 pounds, making storage convenient. The device includes a 24-month warranty and 24/7 customer support.

• MF100 Electric Air Duster: was $89.99 now $59.83 — 150,000 RPM turbofan moving air at 45 m/s, rechargeable battery with up to 100 minutes runtime, USB Type-C charging, five nozzles and two brush tools included.
• Pomels Compressed Air Duster: was $29.99 now $23.99 — 110,000 RPM electric duster with three adjustable speed settings, 7500 mAh battery providing 20-40 minutes of runtime, LED display, five nozzles and four soft brushes.

Regular cleaning with an electric blower handles routine dust removal, but accumulated debris sometimes requires additional power. Traditional compressed air cans provide concentrated force for stubborn buildup, though they're best reserved for situations where the blower proves insufficient.

• Electronics Duster 2-pack: was $11.99 now $6.45 — Two 10-ounce bottles of compressed air designed for electronics, removing dust, skin cells, and debris from keyboards and PC interiors.

Deep cleaning sometimes demands manual work with specialized brushes. Electronic components require careful handling to avoid static damage, though modern parts are less sensitive than older generations. Nylon anti-static brushes in various sizes and shapes remove dust from components and drive bays while preventing caked-on buildup on fan blades.

• Computer cleaning brush kit: $7.98 — Multiple brush types for deep cleaning PCs, keyboards, and internal components, plus keycap puller and tweezers for detailed work.

Isopropyl alcohol serves as the final cleaning product for PC maintenance. While 99% concentration is stronger than necessary, it works effectively for electronics. Some users dilute it to 70% with distilled water for extended use, though the full-strength version performs well as-is. Applying IPA to hot components causes rapid evaporation, which is actually useful in electronics hobbyist circles for identifying overheating chips.

• One Gallon of Isopropyl Alcohol 99%: was $29.99 now $25.99 — Bulk purchase option; decanting into smaller spray bottles provides economical access to large quantities.
• 16 Oz. Isopropyl Alcohol: was $6.79 now $5.76 — Amazon Basics 91% concentration, smaller and more affordable than gallon sizes, performs effectively on PC components.

Thermal pastes

Thermal paste etiquette — pea-sized blob, an X, or a smooth layer like peanut butter?

Thermal paste, also called TIM or thermal interface material, bridges the gap between hot components and heatsinks or heatpipes, transferring heat away to keep systems cool. The application method—whether a pea-sized dot, an X pattern, or a thin layer—matters less than ensuring proper contact between surfaces.

Tom's Hardware's Editor-in-Chief Paul Alcorn uses MX-6 as his preferred thermal paste. A convenient kit containing 4 grams of thermal paste and six cleaning wipes simplifies the replacement process. The wipes, essentially isopropyl alcohol on cloth, remove old paste, dust, and debris before applying fresh material.

• MX-7 Kit: was $16.99 now $9.57 — Contains 4 grams of Arctic MX-7 thermal paste (latest formulation) and six MX Cleaner wipes for surface preparation.

Thermal Grizzly's Kryonaut Extreme ranks among the outlet's highest-rated thermal pastes, outperforming many competitors in extensive benchmark testing. Its primary strength lies in performance under extreme temperatures, particularly in sub-ambient cooling applications.
