Intel stock CPU fan problem

Remus Dascalu · Jul 30, 2014

Hello guys, two days ago i build my first pc.
Here are the components:
i5 4590 cpu
Gigabyte H97-D3H motherboard
Kingston Hyperx black 8gb dual channel 1600mhz (NOT the xmp version) memory
Seagate 1tb SSHD hard drive
Wi-fi PCI adapter TP-LINK tl-wn751nd (150mbps)
an old asus optical drive
Cougar Archon black case
Corsair cx-500 psu (500w).

I made this pc for:multimedia(movies, music), web surfing, light gaming (League of Legends), and for a future upgrade with a mid-high-end gpu(this is when i will start heavy gaming).

Everything seems to work, but i have some issues:
1. when i start my pc, the cpu fan is moving(it tries to spin, but it is actually just moving a little) twice upon 3 seconds, then starts at max speed and sounds like a car engine. In next a few seconds, it gradually returns to is't normal speed, and works just like a normal cpu cooler.
Note:this doesn't happen when i reboot my pc, only when i power it on.
Can somebody tell why is this happening and how to fix it?
2.My wireless PCI adapter has a very unstable and slow connection and i'm thinking of returning it.(my 4 year old laptop has 3 times better connection in the same place).
Also, when i hardly use my internet connection, i start hearing an annoying noise in my speakers....
Has anyone any recommandation for another wireless adapter that has a stable internet connection and a average download speed (30-40 mbps), and doesn't has any interference with my speakers?
i have pci, pcie, and usb slots free, so i accept any recommandation.
3.Immediately after intalling windows and starting to intall drivers and programs, my SSHD started to have some odd sounds, like crackling of the old HDDs. This only happens when i work with big files(moving files, archiving, antivirus scanning,..)
It's WEI note is 5.9, which is also pretty strange, cuz my 4 years old laptop hdd(which is very slow) has 5.8, and it doesn't make any noise.
As performance it works good, windows 7 64 boots in 10-13 seconds.
Why is the NEW SSHD making this sounds?

Sorry for my bad english, and please help me, i'm 16 years old, it's my first built, and i don't know how to fix these problems..

Sorry again for my bad english

As to your first so called problem, it is not one.
On the first power up of the computer it does a series of checks.

One of them is to check for good power from the three power phases provided by your PSU in the system.
If all three phases 12v+ 5v+ 3.3v+ are deemed ok and with in the required ratings then your fan begins to spin at full speed on your cpu cooler.

Again this is a test to see if the fan is Spinning and working also at the correct speed or its highest rpm stated.
In your bios section of your motherboard you have settings where you can set the Rpm or rotational speed of this.
Why it does it is a form of calibration.

What it is doing is working out the maximum rpm the fan can spin at in some cases.
Linked to it is the temp sensor of the cpu core die. and when the cpu starts to get hot it ramps up the fans rpm speed to push more air through the cpu cooling block at at a higher speed.
This keeps the heat generated by the cpu in check.

Now if you leave the settings in the bios of the mobo to auto this is what happens.
But you set your own settings manually.

Any sort of crackle or static noise can be one or two things, first of all feedback from a set of desktop speakers with its own amp, where it is placed too close to the physical tower.
Basically move any amp or other power source that are contained in a set of desktop speakers away from the computer case.

Thank you very much for your fast answer.
Ok, i got it.
Has someone any recommendation for a wi-fi adapter?(PCI, PCIE or usb)

Thank you again

I currently have this (http://www.amazon.com/TP-LINK-TL-WN881ND-Wireless-Express-Low-profile/dp/B0079XWMEI/ref=sr_1_1?s=electronics&ie=UTF8&qid=1406724510&sr=1-1&keywords=tp+link+881) for my wi-fi adapter. I haven't fully tested it out, but so far it has been working wonders and reviews are good.
