I mean of course the pump might not run at 2800rpm even though it’s saying so, but since the value’s jumping up and down around 2780-2820, and getting lower when i put it in silent mode i’m assuming it’s working as it should. I can also feel small vibrations coming from the pump. but yeah it doesn’t feel right with 95 degrees spikes for a 280mm cooler on a 8700K at ”only” 4.7 Ghz. My CPU is NOT delided though. however on idle im getting 35-38 degrees and in less intense games around 55-62, but then again whenever background applications are running i get these spikes at up to 95.

Alright. What is considered a stable voltage for 4.7/4.8Ghz?

Hm.. well everything is mounted as it should. Pump running at 2800rpm, replaced thermal paste 3 times with same temps..

Yeah AVX offset -300Mhz. And like i said he’s getting a top peak at around 86 when stress testing at 1.350V. But somehow i get 10-15 degrees higher peaks. I tried putting everything back to Auto settings and tried with MSI Enhanced turbo which runs it at 4.7Ghz with auto voltage (max 1.350V), but still in a run of Flight Simulator 2020 as soon as it loaded in the textures and map it quickly peaked at 97 degrees and went back down to around 86. I’m seeing 97 at the hottest core, yes. Yeah i know stress tests pushes it to the limit, but like i said 97 degrees spikes in Flight Simulator doesn’t feel right..

Well, guess i'll have to deal with this then :')

Hm alright My friend that has the exact same case, CPU and cooler is only getting top spikes at around 86-ish.. we even use the same thermal paste. Aswell as he's running at 5Ghz with offset at -300Mhz. I don't get why my spikes are getting so high, ran another stress test and got 100 at the highest point.

Hey! I just mounted an NZXT Kraken X63 because I wanted to overclock my i7 8700K. I clocked it to 4.8 Ghz at 1.350V but I'm getting very high temperatures during stress tests. Have tried various stress tests such as OCCT, Intel Burntest and with all of them the CPU sometimes comes up in spikes at even 97 degrees, and steady around 89-92 degrees. In for example BFV which is pretty CPU demanding, I am at about 77-82 degrees, while in Rainbow Six Siege around 55-60 degrees. I have connected everything correctly, the pump runs at 2800rpm, the fans are connected to SYS_FAN on the motherboard so that I'm able to make a custom fan curve. I have tried both Arctic Silver and Thermal Grizzly thermal paste with only minor changes. Also tried to run without overclock but then it's only about 2 degrees colder..
