So i feel like i've been having temp issues, or higher running temps on my brother's E5-1650 (v1). I know it runs hot but something seems off. Motherboard is an EVGA X79 SLI, has 4 sticks of 4gb DDR3 1600 Corsair Vengeance LP @ 1600mhz.
Originally i was able to get to 4.5ghz @ 1.394v with max stress testing using p95 peaking at 85-87c. Vdroop configured as "disabled." I figured this was okay, most stuff wont stress the CPU that hard. Eventually the bad airflow of this case (Raidmax Delta, think like Phanteks P400) eventually caused this to run hotter and hotter once i gave the system to my brother. I brought the OC down to 4.2ghz @ 1.280v and this seemed to peak at 82c in the same environment. Then the pump on this Arctic Liquid Cooler 240 died, and i threw on a Hyper 212 evo which i had to run the CPU at stock mutli with 1.2v vcore to stay manageable. Then in that same case, the EK Fluid Gaming 240 CPU only kit was added and i got the OC back up 4.5ghz at 1.394v at better temps, but eventually this too deteriorated. My brother had to resort to using his PC without the front panel on (rad was on front intake). This made his rad get super dusty super quick and things only got worse. Eventually, it appeared the plastcizer on the tubing of the a240 kit leeched into the block and i had to put the CPU back to stock settings to run acceptably (still without front panel).
Then my brother got an Inwin 303, mayhems tubing, and redid the loop and got the block and stuff cleaned out and its back to normal. Here is the system:
There are 3 fractal venturi fans on the bottom, 2 of which the big ass Gigabyte Xtreme Gaming 980ti gets in the way of, and 1 of which the DDC pump/res is mounted on top. So i imagine airflow upwards is sort of...not at its best. The radiator is mounted up top behind those EK Vardar fans and the rear fan, originally set up as exhaust, has been flipped to intake.
Now this time, 4.5ghz at 1.394 was too hot. I had to adjust the voltage down, and bring the OC down to 4.3ghz to get mid-to-high 80s C in p95 smallFFT (15 mins). HWmonitor reported 215w of power usage on the CPU. Left it there since i ran outta time, but seemed okay. Initial streaming (OBS x264 encoding) + gaming had it stable at mid-60s C not breaking 70. My brother reported the occasional crash to desktop/blackscreen/etc so i bumped the voltage up a notch. Then over the weekend he said he was running 82c across all cores while gaming + streaming and wanted the OC backed off again. Actually he demanded it back at stock, so i set it back and ran p95 SmallFFT again. 80c peak, no OC and stock/auto voltage. Okay now, what the hell? Reset bios to optimized defaults and started over and now temps were high 60s/low 70s at stock under p95 smallFFT, but HWmonitor reporting 180w of power usage. I noticed vdroop went from "disabled" to "intel SPEC" when i reset the BIOS. Left it on auto, upped the multi to 40 for 4ghz and hit p95 smallFFT again. Reported power usage of 194w, temps from high 60s to mid-70s. Ran it for like 30 mins while browsing and doing other stuff to stress it out. Seemed solid as a rock. Gaming didn't break 60c. He hasn't had time to try streaming + gaming again, but it shouldnt be higher than p95 smallFFT (well thats what i told myself before but he still claimed 82c across all cores which was maybe 3-5c off p95 smallFFT at that point in time). So the intel spec vdroop setting with voltage on Auto and multi at 40 has it pushing 1.31v (according to HWmonitor).
Now im thinking it runs everything great at 4.0 and my brother doesn't want to deal with crazy temps anymore. How should i approach this now to bring temps down? Should i manually set voltage to 1.2v and see how it responds? This has been a weird ride with this Xeon.
