e4300 Overclocked Load Temperature Question

I have an e4300 and I finally got a board capable of overclocking it a bit. So right now I'm running 3.0ghz, and it's passed 5hrs(and counting) of orthos small fft. My "problem" is that the temperature reported by coretemp is VERY high IMO. It is 77C under load :eek:, but like 35C idle. I'm using 1.4v and have the intel stock cooler installed with AS5 (grain of rice...). This seems crazy hot to me, but it is passing orthos and isn't going into "thermal protection." Is this temp acceptable? I've never wanted to see more than say 60C load on any of my cpus, but this was before these programs started using the "digital" probes, so I think these temps might be higher because it's measuring closer to real core temp. Speedfan is reading exactly 15C lower, but I understand this is some kind of "bug." Final note, the heatsink feels barely warm (slightly higher than room temp) to the touch, usually when a cpu is running 60C+ it's too hot to touch the heatsink for very long. I know the the heatsink is "snapped in" fully and is making contact, so I don't know if it's a temperature reporting error, or what's up. Any input on any of this would be appreciated. Thanks in advance.
 
I had my E4300 running at 3.3 and it had load temps in the low 70s. 77C is a little hot for that speedbut you are pushing pretty heavy volts, and those chips seem to run hot, so it is probably not a huge problem. Check and make sure the heatsink is making good contact. But if it is passing Prime I wouldn't be terribly concerned about it.
 
1.4v is heavy volts? In the Core 2 Database, e4300 users are using between 1.3 and 1.62v. Also, on intel's website, they list the voltage on the e4300 as "0.85V – 1.5V." I guess 1.4v is maybe a little high volts for the stock cooler though...idk, I mean it has a copper core and all. :p

Ahh, you know what, you're right. I've been thinking E8400 so much lately. I had 1.3625 or something like that in mine, with low 70s, so 77C with 1.4 tracks with what I had.
 
The computer passed 14hrs of small fft orthos, but then suddenly just rebooted. :( In the orthos log, no error was detected, so I don't know what caused it. Windows log just says "unexpected shutdown."


I don't really want to change to an aftermarket cooler. If I did get one, I would need one with a low profile, as my stock heatsink is about as high as my case will allow (matx...). I doubt there are many "low profile" 775 coolers that will cool better than stock and don't sound like a jet taking off.
 
Interesting, I had the instructions from when I used it on my amd dual core, and it said grain of rice in center. I didn't realize that you apply differently for intel duals. Honestly I doubt it will make any measurable difference, but I will try to reapply when I have time.
 
I reapplied the grease following the intel dual core instructions, with no result. :confused: Almost exactly the same temperature reported, 77C load. It actually toggles between 77 and 78, but mostly on 77. It seems to run stable and not restart @ 2.9GHz. At 2.9GHz the load temperature is 70C. I'm wondering if (A.) I got a chip with a poor internal thermal interface between core and IHS, (B.) I got a heatsink that just doesn't sit flat or is not shaped "just right," or (C.) the stock intel heatsink just sucks :rolleyes:. Another thought regarding why it could be passing orthos @ 3.0GHz for 14hrs, but then just randomly restarting is that maybe my psu is being flakey. I notice that the 12v rail goes from 12v down to 11.7v load. That shouldn't have anything to do with my high temps, but could (potentially) be my restart problem. It doesn't seem like much voltage difference to me, but maybe that could cause problems?
 
I wonder if it makes a difference how much you use. The instructions with my Zalman 9700 mention coating the heatsink and the processor heatspreader spreader with a coat of thermal grease. I used the Zalman thermla grease supplied with the cooler. Maybe Arctic is different?
 
Check out the Blue Orb II. Good cooler for mATX cases that does a damn good job. You really want to keep the upper end of your temps around 60C.

The real question is, whats the highest temp you see in gaming/photoshop/porn surfing? Check your temps on what you actually use the computer cause I'm going to bet it never goes above 60C unless you're a folding nut...and if thats the case then who cares? Synthetic benchmarks for temps arent exactly super useful as they are...synthetic, not a rep. of what you are really doing with the machine. Make sense?
 
Hmm, well I have a CNPS7000 AlCu that I could (theoretically) put on, but doing so would be a total PITA. First I'd have to buy the 775 adapter plate. Then, since it's in use, I'd have to remove the board that it's on to get it detached (and replace it with the stock cooler again), and also remove the board in the rig that I'm working on and do the swap. Are there any decent "flower" (like the orb or zalman) style coolers that attach with the push pins like stock?

I like this cooler, but it also requires mobo removal and a separate fan to be purchased.

This looks like it might work ok, and it uses the push pin attachement style, which makes it simple. Any chance it'd work better than stock? I'm thinking it might be worth a shot.

Edit: BTW this unit is my HTPC, but I also use it for gaming and as a "backup," FWIW.
 
But the thing is it doesn't even feel hot. The cooler feels like room temperature. :confused: Can coretemp be wrong? Can a cpu be hot, but not the heatsink? (it is installed correctly)
