Should I re-apply thermal paste?

blelink129 · Aug 11, 2014

I recently re-applied thermal paste, but when I applied it I pushed down on the cooler and than realised I had to turn it. I picked up the heatsink and pivoted it and placed it down again. My temperatures are fine, under load only reaching 60 celcius (Also CPU is overclocked to 4.0 Ghz), but the fans on my computer have gotten significantly louder. Could this be because I applied the pasted wrong? Here is what my speedfan looks like.

Should I re-apply or am I fine? The cooler I am using is the Thermaltake Water 2.0 Performer.

If your fans are having to work harder to maintain that CPU temp (I'm assuming the fans are on a CPU temp-based profile), then I think it's likely that you either got some air bubbles when you lifted and shifted, or that the paste got unevenly distributed. When in doubt, repaste.

Edit: I should have asked - when you say "under load" do you mean during stress testing (i.e. AIDA64, Prime95, etc.), or during regular use? When doing before and after temp comparisons, you need to make sure you're comparing apples to apples. Best way to do that is to set all of your fans to max during any test. That way the temp differential can be properly attributed to the CPU/CPU cooler. 60C isn't a bad temp, but without a credible comparison there's no way to check if it's better or worse than before because of variable fan speeds.

I don't believe you need to no. If your temps are staying under or just above 60 C you are fine. Also your idle temp is fairly good being under 30 C. I would say you are fine. I can't tell what voltage you are at but everything seems fine to me.
In terms of the fan speed are you using the fans that came with the cooler? Also, 1500 RPM you will definitely hear it are they connected via the motherboard, or through the unit itself I'm not familiar with thermaltake water coolers. Ideally you would want your fans probably in the ballpark of 1200 RPM which is the lowest RPM your fans can go by there rating. 1200 is more then enough I'd say. Your fans can go up to 2000 RPM which would DRIVE ME BONKERS! Another option would be to pick up new fans and replace the stock fans. I would go with one of the two options at the less expensive side of things and the more expensive Noctua's.

Also use realtemp or hwmonitor instead speed fan is a bit cluttered

If you look at his temps they are fine. Its just what the fans are doing that is not. There lowest RPM is 1200 RPM if they are the stock fans which is fine but when you move beyond 1200 it gets nuts and take a look at his AUX fan 1900 RPM that would make people go nuts. In my opinion what needs to happen is one of two things.

1.) Manage your fan settings via the bios
or
2.) Change out fans to stronger static pressure fans and fans at a lower RPM

IMHO
Fans that are above 1200 are going to drive you nuts RPM wise 800-1200 is probably a good sweet spot. This goes both for CPU and Case fans.

The 60 is under load from OCCT. Before the load was 70, but the fans were much quieter. Should I re-paste then?

Not necessarily lower your RPM on your fans to a manageable level 1200 RPM is what I'd recommend. Then post your temps. Also are you using stock fans? They may not best the best fans in the world.

How would I lowed the RPM to 1200?

According to the OP, the fans got "signficantly louder" following the repaste job. If the paste job was the only significant change to the system, it follows that the fans have gotten louder because their RPM has increased in response to the CPU's temps.

Re-doing the thermal paste costs very little in time, effort or materials. If, in fact, the previous paste job was okay, at least he can have peace of mind as far as that's concerned, which he obviously doesn't have now - otherwise he wouldn't have posted in the first place. If it wasn't okay, he should see the difference in his temps. The fans may or may not be an issue, but eliminating the paste job as a possible complicating factor would be helpful with that, too.

While he could re do the thermal paste. What isn't said is whether or not he had overclocked prior or after the re application of thermal paste. His can fans are to high RPM wise as well as his CPU fans. So I don't know if the fan speeds were set by him set by speed fan set by the bios it's not clear. The unit he has is not software controlled so its one of those 3.

The computer I have is from CyberpowerPC. I had them overclock it when I first got it. I just re-pasted and the fans have not changed but I did not change the fan settings in the BIOS. I'm not sure but when I did re-paste the first time the fan speeds increased.

I re-pasted again and the fans have not changed. Not sure what it could be.

Do you have tech support with Cyberpower? What you need to identify is whats controlling the fans. If you contact them you need to let them know the speed in RPM that your fans are operating at.

I bought this PC roughly 2 years ago and my warranty is up with them. It also seems that after this repasting I have lost my 4.0 overclock.

You need to do some looking into your bios to see what the settings are setup for. It's not clear what your 4.0 Ghz overclock was set to voltage wise. Also, you need to open up your case and see how your fans are connected are they connected to the motherboard are they connected to a controller? I think you need to do some investigating. Your fan speeds are higher then they need to be for operation, you lost your overclock? how did you run across that, did you touch the bios and change a setting. I can only go at this from the stand point of guessing what could of taken place.

The fans are connected to my Motherboard, and I looked in the BIOS and the voltage was set to Auto.

Okay so that gives me a bit more that we can go off of. So currently your CPU is running at stock it sounds like is your core clock freq left on auto as well? Also have you taken a look at your motherboards fan control settings are there fan settings you can see within the bios?
