Thermal paste

[collierooh]

When building my pc I had put on the cpu cooler with pre applied thermal paste , it had been on there for around 15 minutes when I saw an amd converter bracket and I thought it had to go on so i took the unscrewed the cpu cooler but quickly realised that i did not need to use the amd bracket and the cpu cooler was off the cpu for around 10 seconds before I screwed it back on , do I need to re apply the thermal paste or will it be fine ?

Again that depends on the test; and if the Temp continues to rise higher.

I've done plenty tests on various configs over the years, to where soon as the test starts, within 5-10 mins the Temp jumped up to around 70-80*C range this quick. Stopping the test, the temp leveled back out at around 30-32*C within a matter of seconds. The temp going up and down this quick is normal. However when it continues to rise more and more... that is a clear sign something is just wrong with your overall cooling/airflow setup.

Then you need fans at Rear/Top for exhaust; you have literally nothing sucking out the heat. It will just continue to build up and get hotter the longer your run the system while under stress.

Which Case do you have?

Corsair 460x, and i thought that the fans on the liquid cooling would extract?

Might be a good idea to just list all your specs.
As well as the Liquid Cooler you are using.

If you are reaching that hot on liquid cooling; something is seriously wrong.
Either the Fans on the Radiator are not increasing is RPM speed like that should be doing, or perhaps all the fans are point the wrong way, etc.

Cheap liquid coolers (basically all of those "All in One" units under $200 or so) tend to be hit/miss; if the Pump has any issues, well the entire LQ Unit is going to fail and become useless.

I would double check the paste is good (not too much or too little)
And that the Pump (this should plug into CPU Fan Header #1) is working properly; as well as all your Fans. Your fans should be ramping up/down in speed depending on Loads/Temps

If you have an "i" model of Corsair LQ-AIO Unit (like H100i / H110i) you can monitor and control that with Corsair Link software (provided the USB cable for any "i" model device is connected/working)

Check that the Mount for the Pump (on the CPU) is properly secure all the way. If loose, it might not be making proper or even contact with the CPU.

i have checked all this but ive kept prime 95 on for a bit and it was at 80 degrees for a few minutes but then it dropped to 60 and now creeping back up, is this normal ?

Possibly... as perhaps the Fans aren't reaching an RPM high enough until around the point the CPU reaches 80*C ranges, then they kick into higher RPM, the CPU gets cooled, then once cooled the RPMs drop as it's no longer needed.

Yes it can be normal for all of this back-and-forth to occur; that is how CPUs / GPUs and Cooling Fans should work in general. Not like the old days where you just turned on your PC and all connected fans run at full speeds all the time, that is generally not needed. Especially with newer hardware that has a dynamic clock range and on-the-fly clock changes it can do, all by itself. The fans are a part of that changing factor; when connected via 4pin PWM headers.

But yea if the CPU is not going above 80-85*C range, then it should be fine.
Again this is in heavy stress tests; whatever those are showing, generally you shouldn't see it peak this high during Gaming.

right , i went onto corsair link and changed the fans to max and thats when the cpu would cool down , on corsair link it says the temperature of the h100i v2 is only 25 degrees when the processor is around 70 does this mean the paste is not applied correctly?

Well no; the Cooler and the CPU are two different things.
And not all apps even measure the same CPU temp.
Some measure the Temp at the CPU Socket (this is outside the CPU)
Some measure CPU Core Temps (this is within the CPU core itself)

Not sure where it gets that 25*C from there; even the Radiator would not be that cool with that 70*C CPU heat running through it.

The 25*C could just be room temp or motherboard ambient temp.

It is very loud when set on "Max" though right?
Generally "Quiet" or "Normal" should be enough to keep the CPU cooled at all times.
"Max" or more for OC'ing or extreme tests. That RPM range it outputs on "Max" should generally never be needed under normal conditions.

Try running HWMonitor from CPUID.com
And while Corsair Link and a stress test is running; compare the Temps you see between Corsair Link and HWMonitor

i have core temp application running while doing a stress test , when the fans are at max it is around 2600rpm and very loud but it keeps the cpu at 60 degrees but when it is in performance mode it is set to 1600-1700 rpm and cannot keep the temp down as it creeps above 80 and stays there

[BoNfiRe]

It can go 84 without issue afaik.

[Bad 💀 Motha]

Not sure what else to say or suggest; cause a H100 or H110 set to Quiet or Balanced, with even the best i7 on LGA 1150 or 1151 should cool enough to where the CPU Temp stays below max at all times. But it could just be that particular stress-test is much more stressful than most.

As Bad-Motha said, I wouldn't necessarily consider this a big deal as long as the temps level out. My 4770k will reach ~70° @ 4.5ghz within a couple minutes of starting Prime95. It doesn't budge from there whether I run it for another ten minutes or another 4 hours though.
