Hi All,
I recently built a new system up. The specs are as follows:
ASUS P5LD2-VM motherboard
Pentium D 925 3.0GHz chip with the Intel heatsink and fan attached
1 Gig DDR2 ram
Geforce 7600GS graphics (256mb)
The case is nothing special, but it has a codgen 400w PSU with a 12 cm horizontal fan in it, and the case has another 2 80mm fans (one at the front and one at the back). The Graphics card also has it’s own fan.
The whole system runs quite wonderfully (especially compared to my old P4 1600 Geforce 4!), but my question is as follows:
The Mobo comes with a temp sensing utility, which is set to send of an alarm at 45oC
for the Mobo and 60oC for the chip (these can be changed, but these are the manufacturers defaults).
I live in Australia and the current max temp in the day where I live is often above 32 or 33oC, and quite often the temp in the computer room even at night is above 25oC (or even 30oC some nights), so obviously this will have some effect on the temps… It is also quite humid here!
After about 5-10 mins of both cores pumping at 100% (eg a taxing Blender Render with threads enabled or a modern game), the CPU gets up to 61oC. I’ve never seen it higher than this but it could get there over time. The mobo also gets to 45 or 46oC quite frequently, but admitedly less so since the second 80mm fan has gone in.
Someone in a shop down here said that theMobo could safely operate at 50oC or above, and I found a site on the net that said that the max safe operating temp of a Pentium D 830 is about 68oC. But I don’t know whether these are accurate or not…
Does anyone have any opinions about this? Does it seem too hot?
This is not normally something I’d notice except that the board came with the sensor utility, I installed it, and, well you know what they say about cats…
Yeah I get the same problem. It’s weird you would think a 12cm fan would be enough. Do they sell bigger fans than that?
Keep the CPU fan blades clean. I noticed after a few months the fan blades get dirty with fine dust, then computer gets very hot and the fan starts up. Switch it off and unplug and clean the blades.
Years ago I had a CPU and it got to 80 degrees and it died.
since you live in such a climate i suggest installing several other fans onto your system or switching to more powerful ones, or you can spend about $150 and get a water cooling system that usually controls the temperature fairly nice
or as i do, simply turn the air conditioner on in my room when im in it… lol
60 degrees C for your cpu is not too hot - on the hot side of things, but not going to kill it. Since it is mid summer, this will be the most extreme heat for the pc. I wouldn’t panic about it.
I had a similar situation with an AMD chip a few years back and eventually, I bought a copper heatsink. This brought the temperature down by about 10 - 15 degrees, as opposed to the standard aluminium one.
Currently, I have one pc, with an AMD2800 chip that has been running hot lately. We’ve had a bit of a heat wave recently and its alarm would go off when its rendering. All I do is to put a normal 40cm fan next to it. That works
However, I would recommend getting a copper heatsink onto your cpu, it makes a big difference.
you can always just open the case and throw a glass of cold water on the motherboard. That should cool it off way quick and I bet you wouldnt have any more overheating problems. I recommend that frequently to all my customers. Of course, it wouldnt run again, but at least it wouldnt get hot. And you could…oh wait, sorry gotta go back to work. Got a call on my GeekSquad tech support hotline…
Get a good thermal paste. Google the forums for the good ones. Apply that to your CPU once. Thats why you have to make sure to get a good one. Cause CPU’s don’t like it if you dismantle the cooler to often. But yours is an Intel so it’s less prone. AMD’s don’t like that at all. AMD recommends a thermal pad for their CPU’s, cause if you push a little bit to hard when mounting the cooler you gonna wreck the die. I killed three AMD’s this way, yep.
Do it once with best paste you can get and leave it like that. Watch the dust as mentioned above, especially if you leave your case open. It attracts dust like crazy when open, thats why computer technicians don’t usually recommend that, on the other hand it gets much less hot.
If all that won’t help, install a five blade fan or an air condition in your room. This way not only your computer stays cool like with a water-cooling. Bloody heat in OZ, i know.
my son has been complaining about his xbox 360 locking up several times in a few hours of gaming. Today we bought this cute little fan assembly (3 muffin fans) that clips on the back of the xbox. Ads say it gets the hottest spot (91 f) down by 10 degrees F (5 C), so to 80 F. Hope it cures the lockups. noisy though.
The problem seems to be, as I said before I think, that the fans are trying to cool the system with 28oC + air of over 60-70% humidity quite often.
My plan is to cut a hole in the case opposite the MB and install a massive twelve cm Fan, and this should help most and it means I can close the case.
One night, I had the case open and a 30cm desk fan blowing right on the MB, but the CPU still reached 60oC after about5 mins of 100% on each core (it was a hot night)!!!
I think I’ll move to scotland…
But to ask again, does anyone know what the max temp that a 3.0 GHz PentuimD can safely run at? I assume that it is over 60oC (i read somewhere that it’s 63. for the 2.8 and 68 for the 3.0)
Most cpus can run at temperatures up to 90 degrees C. Many can go even higher.
However, if you put a huge fan into your box, you’ll only cool down your system temperature. It won’t have much effect on your cpu temp. The only way to cool down the cpu would be to get a better heatsink/fan.
dude, seriously, 60 is fine. That is cool for my system. Also - DEFINITELY clean for dust. I cleaned after my cpus started hitting 84c and now it maxes out at 57 under a full load. I would get woken up by the temp alarm while rendering over night. If you can, get the CO2 powered spray-duster and a mini vacuum, unplug and unscrew your CPU fans (JUST the fans, not the heat sink) if you can, and clean the heat sink with the compressed air. I find a lot of dust builds up in heat sinks and can cause overheating. good luck
Also, newer systems tend to heat up more quickly, to a greater degree but can also stand more heat. I was told most can operate safely below 100C and will only fry after running that hot for a while. This was for AMD Opteron server chips but I think most chips are fine under 80C
Cleaning the dust is good. I usually use my compressor. That blows @ 8 bar and cleans anything. Particularly good for a laptop. Its amazing the amount of dust buildup after only 2 months or so.
