We want to talk about a simple way to install an additional fan.
Practice shows that the second largest cause of computer failure is overheating of the video card up to its complete inoperability. Therefore, you should take care of the problem of cooling the card immediately after it is installed in the computer, as well as when the card is installed in it initially.
The additional unit consists of two parts - the base and the fan itself. The base is cut out of any non-fragile electrical insulating sheet material 1,5 mm thick. You can use an unnecessary printed circuit board with dimensions of about 150x100 mm, removing everything from it, including the foil; small holes can be ignored.
Fig. 1
One of the corners is sawn off at the base, and a ready-made computer fan of size 80 mm for a voltage of 12 V is attached to its place with two screws (or self-tapping screws). The result should be an assembly similar to that shown in the photo fig. 1 With the lower part of the photo (about 13 mm wide), this assembly is inserted into the slot of the computer motherboard closest to the video card.
To correctly form the lower part of the base, you first need to outline the optimal position of the fan relative to the heat sink of the card, and put a mark on the base opposite the slot jumper. In the marked place, a groove with a depth of 7 mm is sawn with a hacksaw, after which it is expanded to 2 mm with a needle file. It remains to remove the material allowance from the sides of the base in such a way that the assembly fits snugly into the intended slot.
Fig. 2
Placement of an additional fan in the computer is shown in the photo fig. 2. Connect the fan to a free 12V power connector. Make sure that the airflow is directed towards the card's heatsink.
Measurements have shown that the additional fan can effectively reduce the temperature of the heat sink of the video card. Thus, at a room temperature of 20°C, in half an hour of operation with the additional fan turned off, the temperature of the card's heat sink rose to 63°C, and with it turned on, only up to 30°C.

Artificial leather for touch emulation
15.04.2024
In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>
Petgugu Global cat litter
15.04.2024
Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>
The attractiveness of caring men
14.04.2024
The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
| Random news from the Archive Gadget for the treatment of seasickness with electrotherapy
16.09.2015
Researchers at Imperial College London have developed a method to prevent seasickness through electrical stimulation. They expect to create a portable device with electrodes connected to the head and put it into mass production.
Transcutaneous electrical nerve stimulation (TENS) has long been successfully used to relieve acute and chronic pain of various origins, including headache. Electrical impulses from electrodes located on the skin above the pain focus stimulate the nerves to block pain signals in the direction of the brain, and the pain is not perceived.
The authors proposed to stimulate the left parietal lobe of the brain with electrical discharges in order to influence the vestibular apparatus of a person and thus eliminate the occurrence of nausea associated with seasickness.
The method was tested by 20 volunteers, including 10 men and 10 women. Electrodes were fixed on their heads for about 10 minutes to influence the current. The subjects were then seated in a motorized chair that rotated and tilted, simulating the conditions under which seasickness occurs in humans while traveling in ships and cars. The scientists recorded how long it took before the participants reported that they were feeling unwell, and then that the nausea had subsided. After the volunteers recovered from the first test session, the second session was carried out in the same way.
The authors noted that the current parameters and duration of exposure selected by them are safe for human health. According to the results of the experience, patients who underwent electrotherapy were less prone to seasickness and recovered from it faster than those who did not receive such treatment.
The researchers expect that in five to XNUMX years the technology will find its way into over-the-counter devices like those already available that use TENS to relieve chronic pain as well as pregnancy pain. Perhaps they will represent a cap with electrodes that can connect to a smartphone and use its processor and battery.
