Is this too hot for a Core 2 Duo?

I've got a C2D E6300 1.86GHz that I've finally decided to try and overclock. I bumped the FSB from 266 to 333 and now 366. I am using stock voltage and it's completely stable but it seems to be running pretty hot now.

I ran SiSoft Sandra's Arithmetic test continuously and got a Max Temp of 72C with 70C being the average and 60C being the lowest (before I started the test).

I just bought a Thermaltake CL-P0114 120mm CPU Cooler from newegg. Hopefully that'll bring temperatures down.

I think I could overclock even higher if I could bring temperatures down. I don't want to bump it any higher right now due to temperatures. I'm probably limited by my ram though. It's only rated for 667 and the smallest multiplier my mobo lets me set is 2.0. So we'll see.

In the mean time, think it's safe to run at these temperatures?
 
That seems problematic...especially consideringthe weakness and length of the sandra test....I imagine in a prolong test that could climb to high 70's low 80's....

We used to get our E6300's to 3.4ghz...You are in the 2.5ghz range which the E6300 with stock cooler IMO should be able to handle a tad better then that...

60c before you started test? That is way to high for idle? Are you overvolting it yet? Most E6300's should do that on stock volts.
 
Google Prime95 and download their program and say "Just stress testing" and get some temperatures using that.
 
Well I went back down to 2.33GHz and installed SpeedFan and here is what is says:

Temp1: 41C
Temp2: 50C
Temp3: -1C
HD0: 31C
HD1: 36C
HD2: 33C
HD3: 38C
Core 0: 57C
Core 1: 56C

Sandra says 57C so I dunno which is correct. What is temp2 supposed to be? I'll try Prime95 and see.

edit: Motherboard is a Gigabyte ga-965p-ds3 rev 1.3.
 
Yikes! I used Prime95 and the temps went up to 81C and my mobo alarm started going off so I stopped the test. This is after lowering the speed to 2.33GHz too so I dunno why it's getting so hot.

I hope the new cooler takes care of the heat problem. I sent the motherboard voltage to manual, then set everything to normal. Sandra says voltage is 1.31v. What is normal?
 
Ok so according to wikipedia the voltage range for this chip is 1.225-1.325. The bios says that 1.325 is the normal voltage so I decided to try 1.225 and see what happens. I've been running Prime95 for a while now and it's hovering around 72C. Hasn't crashed yet running at 2.33GHz.
 
My e8500 with stock HSF ran at 70C (according to CPUID HWmonitor) when folding. Turns out the HSF wasn't mounted properly. Either that or the stock TIM takes a VERY long time to melt and flow on the heatspreader, because when I pulled off the HSF, there were huge voids where there was no TIM. Runs at 55-58c with some old AS3 I applied very liberally; a good application might possibly yield temps degree or two lower. Any chance you've got something similar going on?

I find it hard to believe that your CPU should run that much hotter than mine, even considering the differences.
 
72c @ 2.33ghz is a PROBLEM. i think your cpu cooler is mounted incorrectly. too much thermal paste? too little? screws not tight enough? loose?
my Q6600@ 3.2ghz in a 70F room idles at 40c and loads at 65-70c.

 
While your choice of new cpu cooler is a decent one, I'd have thought you'd have gone with one that's known to cool better for the same $$$, like the Xigmatek HDT-1284EE...same $39.99 price and free shipping, and has been shown to cool quite a bit better than the Tt one you've purchased.

Then, follow LOUISSSSS's advice and make sure you don't use too much TIM when you install your new cooler, no matter the brand. A good guide is Arctic Silver's guide on how to apply TIM...or in the case of a C2D, just a very small blob dead center of the cpu seems to work for most people.

But I think your temps are quite too high, too. I've got a Xigmatek HDT-963, a smaller version of what I linked above, on an e7200 that's OC'd to 3.4GHz, and even under OCCT, or Prime, or TAT, I've never seen anything near your load temps. (I cannot relate my main rig's cpu load temps to yours as it's water cooled.)
 
My E6300 @ 2800MHz 1.36V with Arctic Freezer 7 idles at 39*C and Intel Burn Test max 63*C and that's the highest I've ever seen it go.

Intel site says the voltate range for it is 0.850V-1.3625V

Actually the guide is very particular on how to apply for dual core and quad cores based cpus...it is not a blob but more like a line (rice size). depending on quad or dual core is more about the direction of the line and how long...
 
I put the cpu back to stock speed and I'm still getting around 53C at idle. I'm not sure why it's running so hot. I pulled off the cooler and reapplied a thin coat of thermal grease with no change in temperature. Maybe the stock HSF is defective or damaged. I guess I'll find out when I get my new cooler.

Also, when I took off the stock HSF the cpu didn't feel hot at all. Is it possible the motherboard is reporting the temperatures wrong?

Is coretemp or realtemp more accurate? I'm getting a 5C difference between the 2 programs. (realtemp showing lower)

For a Core 2 Duo you should apple a thin vertical line of paste down the CPU rather than coating the chip. See instructions here:

Definitely sounds like a poorly mounted HSF if you're 100% sure you're running at stock voltage or lower. The CPU may not feel hot if you've already cut power and taken the time to remove the HSF. The heat dissipates pretty quickly. Anyway, why are you attempting to significantly overclock with the stock cooler? You should install the aftermarket HSF you purchased.

Sometimes that is due to a difference in perceived tjunction...

What tjunction does coretemp state?

Then take the temp and distance from tjunction in real temp and the 2 should equal that tjunction number in coretemp....

Let me know if it does....

That's what I did with mine. Worked fine and it's almost impossible to mess up. Many times when people coat everything they put too much.

TJ max in coretemp in 100C. Is it reading it correctly?

You're right; the 5C difference between realtemp and coretemp readings is accounted for since the distance to tjmax is the same in both programs.
 
I recall back on my S3 (and friends DS3) that a few apps incorrectly reported the Northbridge temp as Core temp........did you download Core Temp and check there (instead of Speedfan?).
