Tower computer in new desk with computer compartment - heat?

by lloydg / August 22, 2009 3:43 AM PDT

I own a Dell "tower" model computer for a few years now and have always had it under my desk but out in the open office air. I recently purchase a large L shaped office desk with a cabinet for the computer and a power management console. I noticed that when the computer is running in the cabinet (which has a few 3" diameter holes in the back in side, the fans in the computer go into high speed mode. When opening the compartment I can feel a significant amount of heat. It defeats the purpose of having this setup if the computer is going to burn up unless I leave the compartment door open. Is it okay to let the fans run on high and leave the cabinet closed?

I love those things.

Putting today's machines into closed spaces accelerates not only the fans but the aging process to help spur more PC sales. Your choice here.

Fan operation and heat
by Willy / August 22, 2009 5:51 AM PDT

Newer systems have variable fan operation that kick into high RPM to help cool whatever its cooling. Now, place into a constricted area even one that helps compensate, its not enough, IMHO. The enclosed cabinet even with its own fans will have to work to include the system fans just to maintain a safe level. Should any fan fail or falter the end result is a system bound to fail. iT looks pretty but in the long run, not a good idea. However, time will tell in these cases.

Download and run PCWizard 2009.

Then minimze'll see the system temp in the upper right hand corner of your monitor. Record the temps at IDLE ... with the door shut and then door open. Do the same while you doing some requiring more CPU ...record the temps with door shut and then open. The solution may be to mount a fan at the back of the cabinet to pull the hot air out.

Let us know what readings you get.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
