Ambient temperature is the air temperature around you and the air temperature inside the case. Unless you have a air conditioner or a fan, you can turn down the ambient temp around you, but adding an intake and exhaust fan to the case and removing any obstructions to air flow with help improve case and CPU temperatures. Also look at removing any dust from off the HSF or from inside the case, and its intake/exhaust ducts.
My friend just replaced a faulty intel motherboard. He is using an old P4 630.
The mobo came with the thermal pad and he applied it.
The bios temps show 60C.
Is this OK?
what are the measures he should take, he tried to reapply the HSF with the same temps.
AS5 is not available here in india.
What are the various options he has now.
Is the reading accurate? maybe it is reading higher than it should.. If he can touch the heat sink, while running, it should be on the warm side. too hot, the fan may not be doing its job right or case circulation is bad. . too cold, it is not doing its job and maybe it is not fully contacting the cpu. He has to make sure that all the pins that hold the cooler are fully locked.
Hmmm. Strange, thought that I ws the only one who had this problem. Mine also was around 60 when idle and hit 75 when playing! I also live in a tropical country and turning on the airconditioner always is not an option. I got a cheap-ass Asus P5M2 cooler thinking if i could get any lower temps. It just lowered to around 50~53C and 71C at full load.
What some people don't seem to get is that ambient air is simply hotter in HOTTER countries. Average temps in tropical climates hover around 35~40C while in EU and more northern places in America can be around 20~25C.
I actually gave up trying to cool the thing down since the software that comes with my intel board only points out that around 70 or 71 should be the max temp.
P.S. Along with my cheapo P5M2, i put in Artic Silver 5. The only advantage of the P5M2 over the stock is the really quiet op at full load, for a really low price.
Most aftermarket thermal materials are better than stock. Most often te problem is with the way it is applied. Problems such as your occur when:
1-The layer of the interface material is too thick (normally you would not care whether it is 0.4 instead of 0.2mm but that is the double of the thickness and it doubles the barrier you put on the heat, impeding it to escape efficiently).
2-There is less material than needed (or it is irregularly applied) and air bubbles form between heatspreader and heatsink.
So clean everything and put only a thin and unifrm film of it.
However, don't forget what amnotanoobie said. IMO, you have the wrong CPU for the place you live in: An Athlon64 or C2D would idle only 2-4 °C above room temp.
First of all do not rely on the BIOS temps. The BIOS on my rig run almost 20 degrees hotter than my Speedfan. BIOS shows my idle at almost 70C while Speedfan is much more accurate at 50C. Therefore, download Speedfan at:
(I know that there are lots of other utilities, but I like this one best and I've tried them all).
See what temps Speedy shows you at idle and load. Mine are 50 and 73 with a record high load temp of 96 which is ridiculous even for a Preskillet, but still 20 degrees below what the BIOS shows.
If you have high ambient (and I'm sure you do) then you need to refrig your CPU. Even the best WC rig won't cool lower than ambient. Therefore, your choices are:
1) Go with a Titan Amanda or similar TEC cooler. Good luck as I haven't been able to locate one in Europe so in India they're likely unobtainium.
2) Bring down your ambient temps. AC is the way to go. I had a rig where I ducted air from a window AC right into the case. Brought down my idle to 28C!!!
3) Move to Norway.
You should also check your Vcore. My Vcore is:
And I have always wondered why the heck the 2 was as high as it is and how/if it contributed to my skyhigh skillet temps. Note that I have never OCd anything but my old '69 427 Vette. So I'll turn that around to the forum as a question. Any ideas why my Vcore2 is so damn high???
Do you have any websites that offer Water cooling?
That might be the way to go, since air cooling does depend on cooler climates. Check out the Cooler Heatsink section, and ask the guys in that section what is available in your area that may work for ya.
I find when my room hits at and above 80F, air cooling just loose its mojo to keep things cool.
