What are typical CPU temps for overclocked P4 1.6A?

[gplanet]

I can't stand this heat my Athlon XP 1800 is generating...it's making my room unbearable. My CPU temp is in the high 50's.

If I bought a 1.6A and overclocked it to 2.0-2.4Ghz, what kind of idle temps should I expect?

If it's actualy heating up your room, you may want to consider a cooler case. My P4 @ 2719 maxes out at 58 degrees. I'm using a Super Flower Melody case, and it never gets above 32 degrees.

A "cooler case" will only make my room hotter.

The components in my case are going to dissipate the same amount of heat no matter what is cooling them and what case they are in.


if i have a "hot case" then the heat is contained in the case and not in my room...the solution to the problem is to have components (CPU primarily) that are cooler

This is not entirely true... Well... It's not true at all...

If you had a cooler case, your components would not get as hot and therefore you room would not get as hot...

For instance, try this experiment, turn a burner on the stove to max. Then put your hand over it, not touching it. I bet you will notice that the air around the burner is pretty hot. The same applys for the computer, except the computer blows that air all around making it more noticable all over your room.

Not Nessesarily. If your case is poor ass, then you CPU will sit there and cook itself, you fans will only be usefull in pushing that hot air out. If you have a super flower, the 6 case fans will dissipate heat before it builds up. You see, if your case temp averages 40 degree's, your fans are merely pushing that 40 degree air out constantly, if your case averages at 30 degrees, like it would with a Super Flower, you will be get 30 degree air pushed out. This makes sense logically, and also I have experiences it first hand when I changed cases.

The case i have is a Lian Li PC30 (smaller PC60, two 5.25" instead of four) with the two case fans in the front on high. Power supply is an Antec TruePower 330

Hmmm, that's a pretty decent case. the best way to check how efficient your case is to check the temp when idling, and check the temp when at full tilt. My P4 idles at 38 degrees with case ~31, when at full tilt 58 degrees, my case rarely goes over 33.

If you are planning on getting a P4 to overclock, it will be luck of the draw for temperatures. I suggest you get a P4 with a later packing date, mine was 04/10/2002. P4's seem to idle at a very low temperature, which will help keep your room cool at night and when not doing anything intensive.

 

[gplanet]

My case temperature seems to stay in the low 40s when my CPU is around 55-60C. I almost never do anything CPU intensive so I haven't had the opportunity to check my temps out.

But once I took the sides off the case, and put a 2 foot industrial fan up to the case and i couldn't drop my temps below 35C


maybe the problem is i'm not getting the air out of the case fast enough? my only exhaust fan is the one on the antec power supply. I can add two or three 40mm case fans to exhaust. would this help?

As far as how much heat will go out into your room, the only variable that changes is how fast it exits your case. How much is solely determined by wattage.

But if you can get the heat out of your case faster you can turn up the wattage and the running speed......😀

 

[WarCon]

GYPM,

If you have those two intakes and the only exhaust you have is your powersupply fans, you may have serious airflow disruption which can keep the hot air circulating right over the hsf. Negative airflow has the drawback of drawing air through your drives, which can make them fail sooner do to dust. The ideal situation is balanced airflow. That is rarely possible though, so most people seem to suggest positive pressure so your not dusting out your drives. But adding one more exhaust fan would be much better than nothing, and adding two exhausting in the back (don't know if your case has room for that) would be even better. You could move one of the ones in front to the back to try and balance the exhaust.

But if the problem is that the temperature in your room has gone up, due to summer heat then your CPU temp and System temp will go up accordingly.

Oh and the BTU's of heat coming out of your case are the same (unless the fans add measureable heat). Just with more airflow it comes out faster, but as cooler air. Where now its coming out slower, but as hotter air.

I'm running a P4 1.6A @ a very "conservative" 2.1GHz. I use a PAL 8942T heatsink and Adda fan, and my idle temps are 35 C. At full load (Prime 95 torture test + 3 other apps running), it hits around 45C. Never gone higher than that. Also, I used AS 3 for the thermal paste. My case temps range from 26C to 30C, depending on the load.

I have a P4 1.6a w/ stock cooling @ 2.1ghz. My temps stay well below 40 nearly all the time. Idle about 32 and full load max about 40.

EDIT: forgot to mention I have a Chieftec case w/ 3 80mm fans and a HD cooler fan (92mm) also.

 

[Zukatah]

I am running a P4 1.6a at 2.451 and my idle temps are 34degrees for the cpu and 28 for the case. At full load, I get 31 for the case and 52 for the CPU. This is at 1.65volts and my case is the Antec performance Plus with the 430 watts TruePower PSU. I have only the two stock antec fans on the back of the case and they are thermally controlled, so I can go lower than that.

Hope it helps!

I have to agree, more air ventilated means cooler case, cpu, etc. You may not notice the room getting any cooler, but it will stay cooler for longer period that if your case heated up constantly without ventilation. I recommend you get at least 2 x 80mm fans to exhaust the hot air out the back in concert with the two up front intaking cool air from your room.

P4 1.6 at 2.1 using stock HSF, 42 idle, 49 full load. And yes, I am looking for a new case, mine sucks, even with 3 x 80mm fans. 🙂

i am pretty sure gplanet is right with how he described how the heat works in his room... his computer puts out a certain ammount of heat. period... if his case gets really hot that means that the heat is not being dissapated throughout the air in the room. if the heat is not being disapated (spread) throughout the room the room obviously stays cooler. where did this heat go you ask? well it had to have stayed in teh case making it very hot.
as for his problem of his room getting too hot he needs to either contain the heat around the computer (not good for the computer) or buy cooler running components...

ggplanet is correct. The components in the case dissapate "X" BTU's of heat. No matter how much airflow is in the case, that doesn't change. All of the heat is vented out of the case into the surrounding airspace. There is nowhere else for it to go.

My 1.6A @ 2.4 GHz, 1.65 Vcore idles ~ 38 - 39C and ~ 53C or so loaded.

 

[Duvie]

My 1.6@2.66ghz idles 41c and loads at 52c...on an average day in the last week or so...

At equivalent to xp 1600+ speed which would likely be 2.0ghz ( I will use 2.13 cause I didn't test that speed)....idle was 36c and load was only 45c....


I use an aftermarket fan and not the retail unit...however it only cost me 20 bucks!!!

With retail fan at 2.4ghz I would have likely been right at 58-60c load...

 

[SocrPlyr]

i'm sorry i was incorrect in my previous post... really the room doesn't heat up or cool down due to the cooling fans of the computer, it only heats up and cools down quicker... because the heat is being spread... sry about that, but for sure case fans aren't going to help the situation as has been stated by others... really the only thing that i would ask is why not try to get a cooler running one if it is a problem (money is probably the answer here... but i had to ask...)

Obviously you need more ventilation in your room. If you overclock a P4, you will get about the same amount of heat produced as your current rig.

 

[oldfart]

You would have been about where I am ~ 53 - 55C. You would actually be a bit lower since your CPU needs less Vcore than mine @ 2.4 GHz if I recall correctly.
