Question about HP Pavilion a1620n (882780664494) PC Desktop

1 Answer

I have an a1620n HP desktop and I had to recently get a new PSU 350W instead of the original 300W. Ever since then the cpu fan is running very loud at its max speed (around 4000rpm). It is quiet when the computer boots for a few moments but it then jumps up to a high speed. It is noisy, does anyone have a suggestion on how to fix it? The fan sits right on the MB.

There are two types of PSU (silent an ordinary) so original PSU is silent.

Want to upgrade graphics


Your right, both cards will be quite an inprovement in graphics. Your weak link is going to be the CPU, Your specs say AMD Semperon 3200 1.8GHz. Your power supply is a 300w, right? The EVGA 01G-P3-1302-LR has a MIN. 350w. http://www.evga.com/Products/Product.aspx?pn=01G-P3-1302-LR&seeReview=true, you should be OK. The GIGABYTE GV-R435OC-512I Min. 300w. PCIE 2.0 :http://www.gigabyte.com/products/product-page.aspx?pid=2924#sp Both sound good for you , I have both ATI/AMD and Nvidia in laptops and desktops. I like Nvidia. It's your choise, of course, Both are a lot of bang for the bucks. They do get Hot, so keep them as cool as you can. Both have fans! If the graphics card starts giving you little issues, upgrade the PSU to say 400w. Remember, every device you add requires a bit more power.Enjoy!

HP a1210n power LED on back flashes and unable to boot up computer. Recently installed memory upgrade and had to unplug 20+4 plug from motherboard and plug back in once the sink was charged up. Worked...


Try disconnecting the plug form the motherboard. If the LED stays lit, you may have a problem with something you touched inside. But, if the LED does not come on at all with nothing connected, the power supply is dead. 300W should be enough to run your computer, unless you have multiple graphics processors or too many peripherals, but just upgrading memory shouldn't make a difference. Make sure the memory is seated correctly, maybe try taking them out and putting back in, or check to see if maybe you loosened something inside while you were in there.

I think the fan is making a super loud grinding noise.


I would not recommend this. You could fry your cpu and then you would have no notebook. If you are going to open the notebook make sure there is nothing interfering with the fan. The fan can be replace. Take the fan out and try to replace it, if needed. Do not run the notebook without a fan.

Yes, It is a GOOD IDEA to get a bigger wattage PSU in case that you want to add extras to your HP. No you do not need a new case unless it is beat up, or you just do not like it anymore....
