In the summer, the temperature inside the house will increase, and the temperature of the CPU will also rise. It is assumed that the CPU is running at high temperature for a long time, and the bad phenomenon such as crash, restart, blue screen will follow. Next, the author will introduce several "hard goods" radiators to solve the high temperature troubles for your CPU. The most feared of electronic components is high temperature, high temperature will shorten their life, so in order for the CPU to run smoothly, we must eliminate the purchase of miscellaneous cottage radiators. The radiator can be divided into pure air cooling, heat pipe and water cooling. The boxed CPU is equipped with pure air cooling. The most popular radiator is purely air-cooled. It is suitable for entry-level CPUs such as Pentium and Celeron. , i3, etc. Higher-end processors have to choose heat pipes or water-cooled, especially overclockers, tower radiators or water cooling are good choices. Overclocking three yellow sea luxury version + using tower heat pipe cooling, and using 4 with pure copper heat pipe and CPU direct contact, can transfer the CPU heat the fastest, and the tower-interlaced aluminum heat sink with high efficiency fan can also Further increase the heat dissipation rate, thereby effectively suppressing the CPU temperature. At present, Jingdong sells for 89 yuan, and friends who like it should not miss it. Overclocking three yellow sea luxury version + overall size is 97 (L) x 77 (W) x 125 (H) mm, weight 415g. Different from the general radiator, the overclocking Sanhuanghai Deluxe Edition fins adopt a unique bump design, which further increases the heat dissipation area and improves the overall heat dissipation performance. Edit Comment: Overclocking three yellow sea luxury version + radiator on the basis of the original radiator upgrade, using LED style, the overall operation is more fashionable, very suitable for side through the chassis.

A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire trucks. There are two general types: pneumatic and electronic.
Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire
sirens are either mounted on the roof of a fire station or on a pole
next to the fire station. Fire sirens can also be mounted on or near
government buildings, on tall structures such as water towers,
as well as in systems where several sirens are distributed around a
town for better sound coverage. Most fire sirens are single tone and
mechanically driven by electric motors with a rotor attached to the
shaft. Some newer sirens are electronically driven speakers.
Fire sirens are often called "fire whistles", "fire alarms", or
"fire horns". Although there is no standard signaling of fire sirens,
some utilize codes to inform firefighters of the location of the fire.
Civil defense sirens also used as fire sirens often can produce an
alternating "hi-lo" signal (similar to emergency vehicles in many
European countries) as the fire signal, or a slow wail (typically 3x) as
to not confuse the public with the standard civil defense signals of
alert (steady tone) and attack (fast wavering tone). Fire sirens are
often tested once a day at noon and are also called "noon sirens" or
"noon whistles".
The first emergency vehicles relied on a bell. Then in the 70s,
they switched to a duotone airhorn. Then in the 80s, that was overtaken
by an electronic wail.
