Hot weather overloading my fan.

[Tousdae]

The other day, when it was nearly 100 degrees out, I came home and could hear the computer from the door. The fan was working hard. I cleaned the fan, and it DID need a good cleaning, but it didn't get much softer. After I put on the a/c the fan got quieter than I've heard it in awhile. The next morning was cool and the pc was quiet. When I got home, after the temp rose to upper 80's, it was very loud again. I only have 1 fan in there. The PSU is 800 or 850. I decided that on hot days, I'll just shut off my pc when I'm not using it, but how many fans should I have to support that PSU?

Thank you

Hello Tousdae.



I'd be hard to say how many fans you may need, who manufactured the case and what model is it?

Hello Tousdae,

If you do not require your computer to run when not sitting in front of it, then you might consider putting it in sleep mode instead of letting it stay running all of the time. You'll save money on your electric bill, and it will start up fast when needed.

You can also set your Advanced Power Plan settings to have the Minimum processor state set to 5% under the Processor power management option to not have the CPU run as hard when not needed by Windows 7.



Hope this helps
Shawn

Apart from wasting a lot of energy it is really not a good idea to leave the PC noodling when you are not around. The energy is better used if you set your AC to e.g. 80F - that keeps the mildew out of your house.

To shut or not shut a machine off between uses is a controversy that will rage long after most of us are dead. I always shut mine off if not at home: it's a fire hazard, no matter how benign. I usually shut it off if I am going to be away for, say, more than 30 minutes (no hard/fast rule though). It seems to me I have read many more articles on the tangible benefits of shutting down v. the dubious benefits gained by leaving it on regardless of the time period between uses. I build a new machine about every two years so it is entirely possible that I build anew before any deleterious effects of my frequent ons/offs become manifest. On the other hand, I have used "old" HDDs as backup or utility drives and they forever seem to spin away regardless of how many on/off cycles they have endured.

Regarding the fan speed. Depending on the design of your mobo, as the CPU heats up, fan speeds increase. For me, the first order of business, clean the dust from my case paying particular attention to the CPU heat sink which is prone to clogging with dust. What I do about every three months, is to hook up the hose to my shopvac to the exhaust port and then blast away. I then closely check all of the heat sinks/cooling fins/pipes on all my devices (CPU, GPU, RAM) to make sure they are clean.

One other option (that elicits an "OMG!!" from some) if you continually run hot with the machine on, take off the case side panel that faces your mobo. Then place a small portable fan maybe three four inches away directed toward the middle of the case. This is a fan I have used on any number of occasions. I think WalMart has these for less than Amazon. One of these 8-inch, large blade, high velocity, high volume fans will cool your entire case/components by blasting a stream of air in a 360 degree radius eliminating hot spots/dead zones. The reviews at Amazon testify to the output; one user mentions that he cools his receiver with it.

Now some object that the air is not channeled front to back over the components so that they cool. And it is not: the air is blasted at the components which blasts the heat away. Or, in the case, you can hang as many fans as space/connectors permit.

Finally, you might DL the free HWMonitor which will monitor a variety of temps/fan speeds/voltages, etc. and see what your temps are and how various suggestions you receive effect cooling.

Excellent post worthy of rep, which was just awarded. Keep it up my friend.

Hey thanks - I am truly humbled.

I sometimes worry that I may be too verbose or give more suggestions than are called for by the author of the thread. Your comments are most reassuring.

Shawn, I checked the advanced tab and it's already set up like you told me to set it up. I hope that's not bad news. Thanks for taking the time

Kid - It's this - Lifetime Series Pro 650W Psu. Hmm, I wonder why I was believing I bought an 800/850? Oh that is not what you asked. Well, I don't know how to answer that. I bought a HP, right. It had a 450 psu in it and I swear that case had 6 fans in it. I can't remember for certain the amount. There were a lot. 6 is stuck in my head. The motherboard died. It wasn't even a year old and the motherboard died. I took it to my pc guy and he just gave me a new case. It wasn't until about 3 months later when cleaning my fan the first time that I realized all my fans were gone. So, I don't know how to answer your question. I spoke to him yesterday too. He told me that I don't need any more fans and to shut off the pc in weather over 80. ...

Thank you Monk. I'll download that monitor. I also work part-time on my pc so despite 100 degree weather sometimes it'll have to be used. I'll pick up one of those little fans. I saw them at CVS yesterday.

Thanks everyone for the time

 

[Tousdae]

I downloaded the monitor.
TMPIN0 is at 80 degrees
TMPIN2 is at 98 degrees. Bad?
Fanin0 is 2782 RPM.
The sound is very soft right now. What shouldn't the temp go over??

 

[Bare Foot Kid]

There is an option as stated, take the side panel off the case and aim an electric fan at the inside, just make sure nothing gets in there to short it out; your PC guy is an idiot.


What temp is the CPU showing? That's the one to be concerned with.

 

[Tousdae]

I know he's an idiot. Things he's previously said didn't sit right and that's why I started to come here. I think you've let me know another time that he's an idiot too lol The power he has over me is: I pay for parts never labor. That and also I'll get my pc back the same day I take it in, which is very important when you work on it. I don't have the luxury to wait days for my pc to get fixed.

System fan 1 - 50% across the board
System fan 2 - 69% " "
System fan 3 - 60% " "

Where are there 3 fans? ... I see one fan and there's a fan on my video card. Can't wait to see what the temp gets to be on that video card when it's running.

Ok editing becuz I didn't answer your question. ... It says (I hope I'm looking in the right place) Intel Temps Core0 - 89 ... Core1 - 89

 

[Bare Foot Kid]

What is the CPU temps?

 

[msongs]

installed that hardware monitor but what does it mean...

intel core temps 0, 1, 2, 3 are about 43-47 Cent tmpino (whatever those are) are 43, 39, & 57 Cent. It shows one fan at 1666 rpm but does not show the other fans even though they are running. too high temps? Msongs

 

[msongs]

got the temps down a bit...

took compressed air and cleaned the heat sink and other things, turned the fan to higher speed and got the intel i7 down to high 30's. sounds like an airplane now tho. turned fans down a bit and now temp is about 38-40 C that download is a nice gadget to have. don't run my AC except extreme days so house is often 90 F inside. Msongs PS - is there any way to get the post to look like what I type before I post it, as in paragraphs and layout?

 

[Tousdae]

What is the CPU temps?

Since I guess I don't know what I'm reading here... I will show you everything that shows me a temp.

Temperatures
TMPIN0 77
TEMPIN2 96

Intel Pent Temperatures
Core #0 - 84
Core #1 - 84

Darn, I'll have to see what they were before. I turned the a/c on.

Hitachi Temperature
Assembly - 11

That's all I see Kid. Except the ATI temp and I know you don't need that.

 

[Bare Foot Kid]

Hello again.



If those CPU core temps are Fahrenheit, you have nothing to be concerned with; here are my idle temps.

[Tousdae]

Can I ask some questions? Do you have 3 video cards? If so, whats the purpose? My ATI card got to 140 F. Is that too hot? Then I took the side off the case and put a fan to it. It got down to 118, but didn't stay there long as I continued to play.

Ok then, my temps are ok? What would cause the loudness then? .... only when it's very hot outside and inside? Well, today never hit the temps that it had last week. Tho the computer got loud again this afternoon. I can't remember the darn temps, nothing abnormal or I'd remember. I put the a/c on and the fan on the pc for awhile. It's gonna stink that I have to use the a/c when I really don't need it for myself .. just the darn computer!

 

[HMonk]

@Tousdae

I'm a bit confused by whether you are talking C or F temps. If it will help, in a 75F degree room my temps average (all the following are in centigrade): CPU (Phenom II X3) mid-40s at idle, mid-60s under a load (gaming); mobo: stays at mid 30s regardless of load; two ATi 4830s in XFire array: low 40s at idle, high 40s under a load; 3 HDDs: stay in low 30s.

Running an SLI (NVIDIA) array or Cross Fire, i.e., XFire, (ATi) array links multiple gfx cards together for significantly increased gfx performance. For a host of reasons, I much prefer XFire. Once reason is that an XFire array can mix various generations of gfx cards (to upgrade, simply add a new card to your existing card); in but a very few exceptions, this is not possible with SLI (must use matching generations). Also, if your SLI array uses gfx cards whose speeds are different, the faster card will either step down to the slower card or it will disable the slower card's memory - defeating the purpose of the array. SLI arrays are also reported to be OS sensitive. SLI is also limited to certain, very specific Intel chipsets (mostly nForce) whereas XFire can be used on both Intel and AMD chipsets. In a few words, XFire is more versatile and, I think, easier to employ and more stable.

One other thing to check regarding the loudness - and I'd bet the family jewels on it: check your PSU fan. What happens is, when you first turn the computer on, the fan is quiet; as things heat up the fan (because its bearings are worn/defective) start making a grinding/rattling noise - quite unlike the normal roar of fans.

Cure: most PSUs I have seen use a standard 120mm fan. Remove the grate/cover holding the fan in place and replace it with a standard 120mm case fan.

Hello.

Monk has a point that it may be the CPU fan heating up; just to clarify, the temps you post are Fahrenheit and not C correct, because if the CPU temp you posted is in C it is WAY too hot.

I have 2 video cards running independently so I can run 4 monitors, have a look at the link below to see the ways I've had monitors set up.

I've been doing the "side panel off, desk fan" trick for years and highly recommend it. Recently I OC'd my chip and the temps rose 2-3 degrees c so I set my fan up and run it when the temps creep up. System is nice and cool.
