hey guys

I have received yesterday a Titan Goliath with I7 920 overclocked by OCUK. The cpu is cooled by a Proclima Megahalems cpu cooloer (or at least this is the name on the manual of the cooler :) ).
When i received the PC the Cpu fan wasn't fixed to the coler, probably during the travel to Italy something happend. Well in few mins i put the fan in place even if i'm not sure to have fixed it in the right way. Now while i'm writing this post the OCCT utility report the 4 cores between 46 to 49° at a 2040 cpu frequency. And if i start one of the OCCT test the temperrature reach quite fast 80° and the test itself stop.
Instead while I was playing WoW yesterday the cpu T° remain around 55/60° C.

the question is: are these temperatures normal or I have fixed the fan in a wrong way?

Regards from Italy

OCCT will be set to shutdown when the CPU hits 80c, you should set the temp limit in OCCT to 100c, or either that use LinX for stress testing instead.

Like Al stated already, those temps seem a little on the high side for the Megahalems.

Though, in saying that, all the testing I have seen so far for this cooler has been done with 2 fans fitted in push/pull.

When I was on air cooling using a TRUE with only one fan, my load temps used to hit 85c under full load when running LinX, however, your idle temps seem kinda high as well imo.

What frequency is your chip running at out of curiousity?

I take it that the 2040MHz you stated in the OP was the idle frequency?

Yes is the idle freq

Now i have WOW opened and the cores are at 54°/50° with a very low load on the cpu of less then 20% listening to win 7 64 bit resources monitor.

Is it possible in your opinion that i have fixed the fan in the wrong direction? BTW My case is a Antec 902
 
Fitting it in the wrong direction wouldn't have mattered very much. There's an arrow on the side of the fan, otherwise airflow goes towards the label. You want it pushing into the cooler from the right hand side really.

If it might have come loose in transport I suggest taking the heatsink off and remounting it to check that this isn't the issue.
 
Definitely try reseating the cooler, at 4ghz using a TRUE with a pair of 400-1200 rpm fans my i7 920 hits 73c on the highest core using intel burn test.

Well to me that sounds unrealistically low, I've owned 3 i7 920's and all of them went above 80C under full load at 4ghz, it depends a lot on ambient/case temp though.

If the test is actually stopping that points to an instability somewhere in settings, or lack of voltage. Ive seen i7's stable well above 90C and approaching 100C so I don't think a temperature of 80C is to blame for it failing.

As I said previously, by default OCCT sets the max CPU temp to 80c, and if your chip goes above 80c the app will shutdown, you can manually set the TJMax in the options for OCCT, I had a similar issue myself when I used to use this app, whether this is the problem the OP is having or not, I can't say for sure though.

As for setters temps, there is nothing unrealistic about them, when I had my TRUE with 2 fans in push/pull my load temps would sit around 77c, and the room my PC is in is always really warm, so I don't really see anything out of line with the temps he mentioned.

I use 2 x 400 - 1200 rpm pwm fans on a lapped TRUE black, case intake fans are 2 x 2000 rpm sharkoon silent eagles ran of a fan controller, i usually turn them up to full speed when benching/stressing, they make for excellent airflow through the case. I actually have another 3 of the 2000 rpm sharkoons, id say if i was to put 2 on the cooler id see lower temps again, though i cant be bothered ripping the system apart again to fit them.

I imagine had I lapped the base of my TRUE my temps would have been quite similar to yours.

I was quite surprised at the difference in temps I got when I first fitted the 2nd fan onto my TRUE, it went from 85c, right down to 77c!!

The base of both TRUE's I have here are horrible, they are no-where near flat, and there are machined marks over the entire base as well.
 
Aye, mine was really bad as well davy, i first got it for a q6600 i had a while back, prior to lapping both the cpu and cooler my load temps in p95 small fft were hitting 81-81-72-72, managed to knock them down to 68-68-62-62. Both cpu and cooler lapped to 2000 grit, the q6600 was clocked at 3.8ghz on 1.51 vcore.
 
HEy

Thanks for all your suggestion.

this morning I have changed the position of the cpu fan. First time i put the fan in the "front" side of the heatsink. Today i put it on the back very near to the rear fan of the cabinet. And just to be sure I gave a "half/turn" to the screws of the heatsink.

While i'm writing the OCCT test is running (around 15 mins now) and with 100% load the cores are 75°/72° while in idle the cpu is around 42°.

I think I can say that thank to your advie i solved it.

thank you guys

is was more then likley the half turn on the screws that did it mate....just needed a bit more pressure may have come lose on shipping. Try the fan in the front again should give 1-2c better temps again:)
