| 740283 | 2009-01-19 19:47:00 | I have used coretemp and speedfan and they both show cpu temps of 30 (core 1 ) and 42(core 2) (bug) at idle. The nvidia system monitor shows 39 (core 1) and 40 something for core 2. which program should i go with? When i open my case and touch the heatsink on top of the cpu its not hot. |

| 740284 | 2009-01-19 19:51:00 | Thats a good thing if its not hot, those temps are absolutely fine :) | Chilling_Silence (9) | ||
| 740285 | 2009-01-19 19:52:00 | CPU in your sig?.....HT?....pretty sure core temp is for Core 2! | SolMiester (139) | ||
| 740286 | 2009-01-19 20:19:00 | Haha yeh i changed it straight after my first post :P So Coretemp is right? |

| 740287 | 2009-01-19 21:36:00 | Well, I have had a delta of 10c between my 4 cores, so, it is not impossible. I would however check thermal paste application if it worry's you. What did you use, stock HSF?, pre-applied thermal paste?, or other paste you applied yourself? | SolMiester (139) | ||
| 740288 | 2009-01-19 22:38:00 | The new Core 2 Duos (E8xx) series are tainted with sensor bugs. Some report with better accuracy with different motherboards, some have absolutely garbled readings, etc. My E8400 has that faulty sensor - mid 40s idle and up to 70 load. These are impossible temps as I have a properly seated TRUE120 and I know how much AS5 to use (very little, not 1-2mm some idiots suggest). |

| 740289 | 2009-01-20 08:29:00 | id reset the heatsink or waterblock or whatever your using, my 2 cores are dead on the same temp 90% of the time also try checking temp in bios to give a rough idea of idle temp |

| 740290 | 2009-01-20 11:18:00 | Well, I have had a delta of 10c between my 4 cores, so, it is not impossible. Sol - would be interested to know your current deltas on your quad. I've got a Q6600 G0 running at stock in an Antec 300 (3 x 120mm fans + 1 x 140mm) with an Arctic Freezer Pro7. I used AS5 - and cleaned with the AS cleaning solution. Heatsink is firm (no movement) and paste appeared to be very even and minimal (I follwed the AS guidelines very carefully). I've already reseated the HS twice (changed the AS5 both times) to make sure everything looked OK - mainly because I was puzzled by the deltas between the cores. I have core 1 consistent at about 35C, core2 31C, cores 3 & 4 26-27C. These all at idle - ambient about 20-21C. On load, cores 1&2 get to 55-60C & 3&4 around 50-55C. I thought it was really stange that 2 of the cores always seem to be cooler - even under load. Is that normal? I'm waiting to get to the 200+ hours to see if the AS5 cures and temps drop a couple more deg - then would like to OC to 3Ghz. What sort of temps do you get at 3Ghz under load? TIA |

| 740291 | 2009-01-20 20:07:00 | Brooko, those temps are fine, if a little high considering the ACFpro!. Honestly, 5-8 delta between cores is common. You should never worry about idle temps, as you may only have 1 core working anyway. Load is the only time you need to check temps. I am running 9x334, and during winter the temps ranged between 42-48, with the highest about 50. I have a TJ06 though and the ACFpro is inside a wind tunnel, so my temps are probable 5-7 lower than other ACFpro's. I havent check the temp during the hot summer.... You have 3x 120mmm and 1x140mm, is the 140 a side fan?.....If you have a hot GPU in there all good, however I find the side fan can disrupt the flow of air form front to back, so unless you have positive pressure stemming from more intake than exhaust, the temps could be higher than without the 140mm Just noticed you are down in Invercargill!!, I must say, that a jump from 35 to 55 is higher than I would expect. Mine is only 35 to 45 maybe 50.... Your ambient sure is good, there is a lot to be said for a wind tunnel, isolation does work. If I were you, I would just pop ya voltage up 1 notch from default and give it a try at 333, you should be fine, I dont know anyone who cant get a good temp at 3Ghz on these.... |

| 740292 | 2009-01-20 23:45:00 | Thanks Sol - appreciate the help with this. I built the system from scratch (first build) - so the delta threw me a bit. The case has a 120mm rear exhaust and 1 140mm on top. I added 2 x 120mm to the front intakes - blowing air directly over the HDDs (they range from 21-29C depending on ambient). There's a slot for a fan directly above the GPU (Asus 9600GT) - but I left that one blank, as I have pretty good air flow anyway - I just put a filter across the grill to keep dust out. Both intakes and exhausts running at pretty low rpms (only around 1200) so case is pretty near silent. I could up them if I needed to - but can't see the point at present. May add an external fan controller at some stage. GPU idles along at around 27-28C - most I've had it up to was 50C at load - so it's running really nice. The big jump in the cores was only either running Prime (all cores) or if I was compiling a big app under Linux (adjusted Make concurrency level so all cores at 100%). If I'm doing something like gaming - they tend to be a bit lower. Thanks for the tip on the OC. Will try it next week after I give the AS5 another week to 'bed-in'. Total build (in case you were interested): Antec 300 Case, Corsair 520HX PSU, Asus P5Q Pro Mobo, ACF7Pro, Q6600 G0, 4Gb Corsair Dominator DDR2 1066, Asus 9600GT, 2 x WD Blue 500 Gb Sata2, Samsung 2232BW, Logitech G5 - Wave Kb - 2.1 Speaker system. |
