How hot is tooo hot??

[comphackt]

OK...bought all the components to build a new box. Got a Barton 2800, 512 DDR400 Corsair mem., Abit NF7 mobo, etc, etc. Now mind you Im still waiting for the case to arrive to put everything together...

However, when I hook up my mobo and proc, I am reading CPU temps of 40 degrees C from BIOS. Once again, a Barton 2800 with TR2-M4 HSF with a layer of Arctic Silver 5 on there.

Should it be that warm without doing anything? I mean its just at BIOS and its already 40 degrees? I am thinking about getting a new HSF cause I bought this one more for the looks then the performance. Im NOT an extreme overclocker, but I would like to suck a few more MHZ out of this thing later. but with temps like that Im already hesitant too. When I get the case and HD, Ill hook it up, do some foldin' and see what the load temps are, and the temps after all my OTHER fans are installed in the case. Im sure that the living room floor with just the HSF is not the best place to be benchmarking the Proc.

Let me know if you think thats too hot, too cold, or just right. Thanks!

Totally depends on your case temp and if you used the correct amount of AS5. If your case temp is really high (i.e you don't have any fans, haven't organized cables... you live outside in the Mohave Desert... etc) that will affect your cpu temp. Also, more AS5 is not better... you have to follow their instructions to the letter to get the best temps.

Otherwise, post your load temps and then it will be easier to see if that HSF is going to be a problem or not. 40°C idle isn't bad if your case temp is really high, but if your case is fairly low... you might consider another HSF.

It seems a bit high to me, it could be for a number of reasons though.
it's possible you put on to much/little AS5
that HSF is not the greatest
what's your case temp?

im getting 45C idle with my SP-94 and Vantec Tornado and im begining to wonder if mine are too high. im not overclocked or anything!!!!! i have 3 80mm fans pushing and sucking air and its in an Acrylic Case so it shouldnt be hot!!!!!

 

[Lejend]

Try reseating the heatsink. Sometimes it takes a few tries to get a good fit on it.

 

[Bios24]

loks-
Definitly something not quite right there. With a 35C case temp I can get 41C cpu idle with my ALX-800/AS5/80mm Stealth combo. What's your case temp?

 

[squirtle632]

From what I read in the OP, it seems that he is running this in free air without a case.
Am I correct in assuming this?
If so, 40°C is a bit high is your room temps is of a normal temp like 23-24°C.

 

[sagitta85]

I guess I can be a part of this

My temps as of right now is CPU 46C and Case 25C.

My heatsink is the SP-97 and I use a old Thermaltake fan, which pushes a lot of air.

The heatsink is fitted perfectly and I add the right amount of AS5.

Whats the deal?

Hey i'll hop on too....

My temps are 48-50c idle and my case is 27c. I have a SK-7 with Smartfan at full speed. Perfectly seated with silver thermal compound. I'm also in the basement so its nice and cool. Wtf is up with 50c idle temps?

 

[Enablingwolf]

Well my two cents....
If the HS is rough and not seated corectly it will make the thing run alot hotter. I lapped my stock 2400+ HS and got like 5° cooler temps outta it. Plus I used the latest TIM and of good quality. AS5 (Artic Silver 5) gave me great results after about 6 days, that gave me another few or so. I went from 120°F(50°C) to 105°F in the effort of keeping a cool CPU. Case temp were adressed too.

If it is an SP97, make sure it is mounted correctly. Mounting can make the difference of up to 10°C.

Will post more later... time to clock out!

Well, I believe it is mounted correctly. Does it have to be tighten tight?

Acrylic Cases usually run hotter than metal, aluminum stands the test to run cooler than most. Maybe they should make a copper case, since copper is the best so far for heat conductivity.

 

[PCGUY112887]

It says tighten it till the standoff's for it start to move... well I don't see how they're really going to move and I was very afraid of cracking my core so I didn't go and harder..

 

[CircuitBreaker8]

Well when you see melting silicon dripping from your computer, thats whne you know its to hot

 

[comphackt]

Well I got home from work yesterday to find my case sitting at my doorstep! I love Newegg and Fedex, they ship stuff so fast....anyways....

I put all my system fans in and the temp dropped a couple degrees(from 40/41C), then, as someone had mentioned on another forum the temp actually dropped even more when I installed and booted up Windows XP (Eck! Installing Linux tonight) instead of reading just the BIOS temps.

So now heres what I got for cooling:

TR2 M4 HSF running mid speed at around 30000 rpm (can get up to 4500)
2 80mm Coolermaster red LED fans intake from the side (directy onto the mobo), and 1 80mm fan exhausting out the back below the PS, which has the exhast of its own, and a secondary fan from the bottom which lines up perfectly to blow though the metal sheets of my heatsink. Room temperature is around 24C, case ambiant is 21/22C and CPU temp is 35C. Im pretty pleased with those temps. The case has a good airflow though it. I might even put a top blowhole in it on an upcomming case mod, so that should bring things down a few degrees as well. Soon Im also going to put some time in and lap the Heatsink, that should bring it down a little more. When all is said and done Im hopeful to reach 30C CPU temperatures.

I only installed Windows right now, but soon I will install some monitoring software as well as some benchmarkers (Prime95, Folding@Home, etc) to find some of my load temps. As far as those go, any suggestions on some good ones, those are really the only big ones I know.

Let me know what you all think of the setup and Temps! Lata guys!

Room temperature is around 24C, case ambiant is 21/22C and CPU temp is 35C

You might have the case and room temp mixed up, b/c your case temp can't be lower than your room temp... unless you have an A/C mounted on the side of your computer. Your case sensor might be off too, EnablingWolf is having the same problem with his case temp.

BTW, nice temps! You should be able to reach 30°C if you organize your cables and get some good airflow moving through your case. I think the lowest temp I've seen for my cpu this summer was 29°C( it was at night, and my mom had the A/C cranked ). It might drop a little when winter comes back.

I would highly recommend adding the blowhole, it does help drop your case temps a bit. Organizing cables and removing the alum. case fan grills is another way to lower your temps a good amount. If you want to go a little farther, try cutting holes in the back plate the mobo attaches to, it lets you run your cables behind the mobo, and if you put a fan on the side panel you can get rid of some of the heat behind the mobo. Here's a pic or two, it's a little hard to explain.

 

[sagitta85]

Man, it better start dropping down, because when I play UT2004, it go over 50C. It sucks.

 

[sagitta85]

Ok, I went and reseated my Heatsink and put on a new thermal compound, not the AS5. Also, I cleaned the heatsink and it is smooth as a baby's butt.

I checked the temps and it helped a bit, CPU is at 39C idle and case is at 24C.

Well, I'm off to play UT2004!

 

[mtb856]

Cool ... glad your temps dropped a little. BTW, could you post what kind of fan you're using, sagitta? I'm curious if that could be part of your problem as well.
