How to fix a noisy computer Fan

The computer fans in your desktop PC or laptop are there to keep things cool and running smoothly. However, if you can barely hear yourself think over the cacophony of fan noise emanating from your computer, it’s probably time to diagnose the problem.

An internal fan will work harder as hardware temperatures rise, but there’s probably something more going on if your PC constantly sounds like a wind tunnel. It could be a major issue, a minor inconvenience, or something in between. Here are a few things to try.

Check What Software Is Running

Your first order of business should be to check what software is currently running, the resources it’s using, and whether that fan noise is warranted. In Windows, press Ctrl + Shift + Esc to bring up the Task Manager. In macOS, press Ctrl + Space and search for Activity Monitor. This will show you what programs are currently open and using system resources.

An idle computer should not be using more than 20% of its CPU capacity. If you aren’t doing anything intensive, yet your CPU is busting out 100% of its power, look to see what program is eating up those cycles. Maybe you have something running in the background you forgot about, or you could be infected with malware that is using your PC’s resources without your knowledge.

How to avoid Bottleneck on your PC

A good piece of advice when building a PC is to have a balanced part list, else bottlenecks may occur.
A bottleneck happens when a faster component is limited by another. This refers to CPU, GPU, RAM.
There is a point where, keeping one part the same, having a faster another part is not helpful at all.

Many people build a PC for gaming. A too fast CPU with a too slow GPU (or the reverse) is usually bad.
Instead of thinking about a single performance metric (like FPS), we can use one metric for each part.
We can define a CPU FPS and a GPU FPS, the actual FPS being always the lower value, never the upper.

CPU FPS = FPS when the CPU is the bottleneck – No matter how fast the GPU is, this is the maximum.
GPU FPS = FPS when the GPU is the bottleneck – No matter how fast the CPU is, this is the maximum.
This may be an oversimplification, but the statements above are true within a small margin of error.

CPU FPS increases with the single core performance and with the core count up to a limit (now 6 – 8).
GPU FPS increases when the GPU is better and when the graphical settings (+resolution) are lowered.

In order to avoid bottlenecks when gaming, here are some rules for deciding between CPU and GPU:

  1. The more demanding the game is, the more a faster GPU is needed and the less a faster CPU.
    Actually both are needed, but if the GPU is weak, the game is going to be almost unplayable.
    AAA games are more demanding than e-sports, newer games are more demanding as well.
  2. The higher the graphical settings are, the more a faster GPU is needed and the less a faster CPU.
    Resolution is included in graphical settings and it has values like: 1080p, 1440p and 4K.
    1080p = 1920 x 1080, 1440p = 2560 x 1440, 4K = 3840 x 2160, others are virtually unused.

(!) Some games (like simulation ones) are not graphically focused, they need a strong CPU.

Keep in mind that 1440p is much closer to 1080p than to 4K. The rule: 4K gaming is GPU bottlenecked.
How many pixels? 1080p = 2 073 600 pixels, 1440p = 3 686 400 pixels, 4K (2160p) = 8 294 400 pixels.

Sometimes a bottleneck occurs between the CPU and the RAM, particularly when the RAM is slow.
First of all, 3200 MHz CL 16 is the sweet spot and it should run at this speed on many new systems.
If gaming using an integrated GPU, don’t get slower RAM because RAM is a huge bottleneck here.

The final rule: Always search for benchmarks. Try to find many sources to be sure of the performance.

Ce este Smishing-ul si cum sa va protejati de aceste atacuri

Smishing-ul este combinatia dintre „SMS text messages” si „phishing” ceea ce inseamna ca este un atac de tip phishing care se efectueaza prin intermediul mesajelor text pe care le primiti pe dispozitivele dvs. mobile. Mesajele au in general un continut atragator, incercand sa va convinga sa dati click pe un anumit link.

Dand click pe linkul respectiv veti fi directionat catre un website real, unde vi se va solicita sa introduceti informatii sensibile cum ar fi ID-ul de utilizator, parola sau detalii bancare. Daca dati curs solicitarilor de acest tip veti deveni o victima a criminalilor cibernetici care va vor folosi datele pentru a comite fraude legate de identitate, vor sustrage bani din contul dvs. bancar sau pentru a efectua  alte activitati rau intentionate.

O inselatorie de tip phishing (phishing scam) este o forma de atac cibernetic care va vizeaza pe dvs. sau afacerea dvs., trimitandu-va linkuri sau mesaje rau intentionate prin email, mesaje text SMS sau apeluri telefonice. Daca veti da click pe link sau furnizati informatii confidentiale prin orice cale, veti deveni o victima a acestor atacuri.

Tipuri de atacuri Smishing

Inselatoriile phishing prin SMS sunt efectuate in numeroase moduri. Iata cateva dintre cele mai comune metode de smishing pe care le folosesc criminalii cibernetici in zilele noastre:

  • Mesaje text de la institutii financiare, banci sau companii de asigurari care anunta ca exista o problema cu contul dvs. care trebuie rezolvata rapid
  • Mesaje text care va informeaza ca ati castigat un premiu important, un bilet de loterie sau oferte cu diverse reduceri
  • Mesaje text de la organizatii online care va solicita sa va verificati metodele de plata
  • Mesaje din partea diferitelor organizatii caritabile, pentru a face donatii
  • SMS de la autoritati pentru a afla detalii

Atacuri Smishing: Cum functioneaza?

Atacurile smishing nu sunt ceva complicat fiind chiar usor de intreprins. Atacatorii folosesc cateva instrumente deloc complicate si ii vizeaza pe detinatorii de device-uri mobile trimitand mesaje text. Uneori, escrocii primesc detalii despre victimele lor inainte de a lansa un atac (social engineering scam).

Iata o descriere detaliata al modului in care se desfasoara  atacurile de phishing prin SMS:

1. In primul rand, primiti un mesaj text de la infractorii cibernetici. Atacatorii folosesc numere de telefon falsificate pentru a se asigura ca SMS-urile creeaza impresia expedierii de la o entitate existenta – banca, etc.

De exemplu, daca escrocii au trimis un mesaj ca venind din partea unei banci atunci foarte probabil va vor pune intrebari legate de contul dvs. bancar. Daca fraudatorii detin mai multe detalii despre dvs., atunci ei vor cere informatii mai specifice despre dvs. pentru a va face sa credeti ca mesajul text provine de la un site web real sau o aplicatie pe care o utilizati.

2. Continutul mesajelor text este diferit de la caz la caz. Dar scopul tuturor mesajelor este de a crea un sentiment de urgenta pentru a va face sa luati masuri rapide.

3. Al treilea pas va determina soarta (!!). Daca ignorati mesajul text atunci acesta este sfarsitul acestei inselatorii. Dar, daca dati click pe link veti fi directionat catre un site cu aspect legitim, dar care in realitate este un site fals care imita originalul. La accesarea site-ului, fie vi se va cere sa furnizati informatii confidentiale, fie sa descarcati software pentru a finaliza procesul.

Atacatorii va vor cere sa furnizati informatii confidentiale precum ID-ul de utilizator, datele de conectare la serviciu, detaliile bancare, detaliile cardului bancar, etc. Site-ul web va va cere sa descarcati un program pe telefonul mobil care ofata instalat le va oferi atacatorilor acces la dispozitivul dvs. Acestia vor putea sa va  monitorizeze toate miscarile si va vor fura informatiile despre cont, bani etc.

Cum folosim metode alternative pentru a deschide Task Manager in Windows 10 si 11

Deoarece managerul de activitati este de obicei accesat atunci cand o aplicatie sau un proces se defecteaza, este important sa cunoastem mai multe modalitati de acces. Deci, este posibil sa nu ramanem blocati in cazul in care un proces ne impiedica sa utilizam metoda obisnuita de a accesa managerul de activitati.

Putem utiliza Managerul de activitati pentru a forta inchiderea unei aplicatii pentru a dezactiva procesele ramase dupa inchiderea unei aplicatii, pentru a vedea aplicatiile care ruleaza in fundal sau pur si simplu sa privim starea actuala a resurselor. De exemplu, o aplicatie ne poate impiedica sa utilizam comanda rapida de la tastatura (cea mai usoara metoda), in acest caz, va trebui sa o accesam de pe desktop sau din meniuri. In afara de renumita comanda CTRL+Alt+Delete, in urmatorii pasi o sa prezentam alte metode pentru a ajunge la acesta.
