After my Dell XPS 710 motherboard bit the dust, I tired of the proprietary hardware and salvaged everything and built a new computer. Now that I can monitor temps, I think I may have a problem.
MB temps are running in the 60s Celsius. I'm able to cool it down into the 50s by opening the case and running a large fan blowing into the case.
I had problems with the CPU also running high, into the 70s Celsius, until I removed the Zalman CPU cooler and replaced it with a Corsair H50 cooler. Sweet! CPU now in the 40s with 100% load on the Quad Core Intel CPU at 2.66 Ghz (no overclocking).
Seems like a problem with more airflow needed, but the Cooler Master case has a fan on the power supply (built in, outflow), 120 mm fan on the hard drives (dual 1TB in RAID Mirror), 120 mm fan for the Corsair H50 cooler (inflow), and a 3rd 120 mm fan on the case (outflow).
I have Dual nVIdia GeForce 8800GTX video cards, which I think are the main heat problem. The old Dell had a separate fan on the cards, which I don't currently have.
My MOBO is a ASUS P5N-D.
As I type this, the CPU is at 46C and the MOBO is 59C. I'm running the Quad Core at 100% duty cycle crunching SETI data.
The case is propped open with a desk-top fan blowing over the MOBO. Obviously, I'd prefer to shut it and use the internal fans, but the MOBO temp will rise into the upper 60s low 70s Celsius if I do.
I'm new to this homebrewing of computers, having bought Dells for 25 years or so. Maybe I need a different case that will allow more fans? The ones I have, 120mm, max out at 1800 RPM, yet my BIOS has them running between 1200 and 1800 or so . . . not maxed out.

So, you only have one case fan and it's outflow? IF you can add an intake fan on the side panel of the case that would site you nicely. Also, if you're running your CPU at 100% load then that is an ok temp depending on the climate. I have a Zalman 9500 on my Q6600 G0 cpu and it can go up to 80c if I do a torture test with Prime 95.
Also, what are you using to measure the temperatures? I like to use different programs to compare the temps and work from there.
You can get a better case which has more intake and outtake fans since the fans from the components inside the case won't do much imo.
Everything I write is Sarcasm.
I'm using a PC Probe II supplied by ASUS to monitor the MOBO. Speedfan, another program, gives me the same temperature info so I believe it's correct. The Corsair H50 took up the rear fan, which previously was pulling air out. I had another fan blowing air in. The H50 recommends using the fan with their cooler to blow air into the case. I thus reversed the other case fan, which had been blowing air INTO the case . . . now it's the sole fan sucking air out.
The MOBO goes to about 68 to 70 C with the case closed, just using the installed fans. I'm very pleased with the CPU temps now using the Corsair H50. The room temperature runs typically in the low 80s (lots of ham radio equipment running!). I'm in Florida.
I guess I'll have to switch to a different case that will allow more chassis fans . . . this case is the one recommended to me, bought locally. The invoice says Coolermaster RC-301 but I cannot find that model number on the Coolermaster web site. It has a plastic side where a fan is mounted so one can see inside the computer.
Edited to add: The invoice was wrong. The case is a CoolerMaster RC-310-SWN1
After further review, I found that the majority of Corsair HC50 users mount the fan(s) on the radiator to pull air FROM the inside rather than the company recommended blowing air INTO the case. Why one would want to blow hot air removed from the cooler radiator back INTO the case is unknown to me . . . makes no sense at all. Yet that's what Corsair recommends.
I put two fans on the HC50 radiator in push-pull fashion oriented to blow air OUT, in addition to two other case fans that are blowing air into the case. My CPU temps under 100% load on the Quad Core are running in the 40s Celsius and the MOBO is now running in the low 50s. That I can accept!
Download EVGA Precision 1.95. You can monitor your GPU temps in the task bar. Also set your fans for 100% all the time. The 8800GT's will run hot. Download it from MajorGeeks or Guru3D. The EVGA site makes you sign up and asks a bunch of crap they don't need to know.
EDIT: The graphics cards don't need to be EVGA to use the program.
I am using sony vaio VGNCR343N laptop from 2009 may onwards.. Now i have problem that it turn off randomnly without any reason. if turn off problem started once then it repeat again and again. Sometime it works 2-3more hours without any problem. I think the laptop turn off only, when i am using Visual studio like large applications. Laptop warrenty period are over. I gave it in a service center, they said that some chips in the motherboard of this laptop is complainted and also they have no interest to repair that chips, only interst to replacing motherboard, its cost is 15,000 more.what can i do? Can i replace that deadly chips? please give me a answer as soon as possible.....
Your request would get more attention if posted separately for easier spotting.
First indications are that your laptop is shutting down from overheating, likely due to dust collection inside the unit restricting airflow. You can open the unit and clean this dust out fairly easily - I have done it to several Dell laptops and it really solved the problem for those owners. I do not have the info on that particular model, but you should be able to 'Google" for the procedure to gain access to the innards -- like the total procedure or at least how to get into the unit without damaging it.
