Intel Core i7 860 Idle at 45 Degrees C?!

[jsrober]

Hi,

I'm concerned that my CPU temperature is high. The BIOS Hardware Monitor reports 45 degrees Celcius. When I run Mersenne Prime Search (GIMPS) with 4 cores / 8 threads the temperature quickly jumps to 90 degrees C. I immediately stop GIMPS as I suspect this temperature will damage the CPU.

I removed and re-installed the Intel retail heatsink/fan as I thought it might not be seated properly. It looks like it is properly attached.

Are my temperature observations normal? If not, do you have any suggestions about what I should do to lower the temperature?

I would like to purchase a new heatsink/fan, but I have not seen much information comparing LGA 1156 heatsink/fan components. NewEgg doesn't even have an LGA 1156 category in the product selector.

I would like to hear from others who like the heatsink/fan they've selected and who are using the same motherboard and case then I'm using as I want to make sure the heatsink/fan will fit in my case and will not block any of the RAM slots on the motherboard.

Any advice would be much appreciated!

Thanks,
John

The idle isnt high, but the load sure is.

45C is nothing to worry about. 90C, however... yikes. You should aim to keep the core temp under 80C or so.

There are very few aftermarket LGA1156 heatsinks currently available. There's a Noctua and a Mega Shadow, but those are both $70 or so and IIRC that may not even include the fan(s). For something a bit more reasonably priced -- yet still better than the stock HSF -- consider the Arctic Cooling Freezer 7 Pro Rev 2 (http://www.ewiz.com/detail.php?name=FAN-7PROV2) for $23.99. Make certain that you look for the "Rev 2" model, as the earlier model won't be compatible with LGA1156.

js i have the same setup accept i have the asus pro not the deluxe. i also had the same temp ordeal. if assuming you have everything in bios set to default or auto your idle temps should be high teens to high twenties at idle. my temps read high at first as it took three tries to finally get the hs on properly. take the hs off and turn it over. make sure each of the four nylon mounts has the push pin in the middle of each pulled back. then reseat two diagonally at a time. hope this helps and good luck.

u probably didnt get the heat sink secured on tightly.

Make sure u pushed all the black heads in and you heard it go snap.

DOE... what happened to that gray stuff that was under the sink?
Did u wipe it off? or did i get smeared?
did u lose some of it? what happened to the gray stuff?

That gray stuff is a type of paste, and its kinda important.

High teens at idle? That's unlikely with air cooling. High twenties is more likely... especially if you leave speedstep and other power saving features enabled in BIOS.

Kind of important, HA HA...I would say a little more than kind of

sitting here reading this thread at 20c per speed fan. 1354 mhz @ .880v CPU-Z

 

[fleflikr]

When I run prime95 I have 8 threads running at aprox. 3.0-3.2 ghz high 70c. As I shut down the threads one at a time the speed ratchets up to 4.0 with two threads running. Not bad for a crappy hs and fan.

20*C = 68*F

Wow! That CPU will help to cool your room in the summer!

Speed Fan reads 10*-20* cooler than Real Temp.

Mine is doing 42-46*C at 1200mhz 0.864V in idle and 85-97*C at load. Same situation was with MSI CD53. Applied AS5, was little to no difference in temperatures. The stock Intel heatsink is really inadequate.

 

[jsrober]

What cooler have you ended up using?

Did you give up on 8GB of RAM?

 

[fleflikr]

Thanks for the heads-up GLeeM....didn't know that. Guess that puts me around 30c- 38c.

Update: I feel like such a noob right now. I reseated the heatsink twice and reapplied AS5 but my temps kept climbing into the 95*C range. I finally pressed harder and heard one of the pins click, realizing it wasn't in 100%. My idle temperatures are now 37-39*C and load is 77*C for all 4 cores, down from the high 90s on Cores #0 and #2.

So, OP I would recommend you double check that your stock cooler is actually seated 100% correctly because I thought mine was and I was completely wrong.

Jumpem, I never got the 8GB to work because I had to return the Ram before I put the new parts together Have you seen anyone running DDR3-1600 8GB on P55 yet?

I have read that anything over DDR3 1333 will only work for two DIMMS. DDR3 1333 is the maximum supported to use all four DIMMS.

I have no first hand experience, just what I've read.

I am running a i7 860 ocd 3.15ghz on aftermarket cooler. Idle temps are 38-41 ... Is this a decent temp for the medium oc i have?? Running prime95 , the highest my temp got was 76 ... Can someone with a similar system compare and respond?!

Read Russian's post above (marked Update:). With his heatsink clipped on properly, his temps match yours.

Not if you use the latest version. Speedfan, Coretemp, Realtemp: all same temps here. Bios will give slightly higher temps (i think because energysaving features arent active yet).

I would recommend Thermalright MUX120, good cooling, quiet, doesnt block ram slots. Or Coolermaster Hyper 212.

High teens low 20's idle on air? Not likely. Unless you're living in a freezer or something. 20c would be 68F. 20c idle isn't even going to happen on water unless you're living in a really chilly room and running at stock speeds or something. ^_^

yeah, those numbers don't mean anything anyway. the best way to look at temps is distance to tjunction. if your tjunction shows 100c and you're at stock loading at 90c, your distance to tjunction is only 10c. if that is the case, then you have a hsf problem. probably as aigo says you need to make sure it's on there tight and that you have the proper amount of thermal paste.

btw, I routinely load in the low-mid 80's running dc 24/7. I've oc'd and overvolted all my cpus to the generally recommended limits and have never had one fail. I keep waiting for it to happen b/c I'm champing at the bit to upgrade one of my rigs, but they just won't die!

yes, but russian is loading his more than prime 95 loads, plus he's doing it 24/7 at 3.9 instead of 3.15.

@apawk, what aftermarket cooler do you have?

Hes also running a stock cooler :-( Im running an aftermarket cooler... one would think i would have slightly cooler temps than someone with a stock fan:

Man, those detonator links are annoying as hell--reminds me to turn ad blocking on lol...anyway.

Well, that cooler isn't great, but it sure is better than the stock one. You may want to try re-seating it and re-applying your thermal paste, making sure to do it properly...However...

We are missing a big piece of the puzzle here. One that makes all the difference in the world. What is your room temp?
