Corsair H50 running really hot

post #1 of 50
Thread Starter 
So i recently started to overclock my PC, and when i've gotten stable around 3.8-3.9ghz range, but my temps are in like, the low/mid 70's and sometimes even up to 80. Luckily no higher than 80 though (if that makes it any better). I'm pretty sure i should be having temps in the mid-60's region under full load, or at least that's what i want with a pretty hefty overclock.

any tips on what i should try before i try OCing again? i already tightened all the screws on the h50 a bit if that helps :/ if there's any BIOS settings i should change or know about that'd be helpful too.

that's what i figured...do i have to like scrape off the H50's default paste first? also does best buy even carry thermal paste so i dont have to drive an hour away to go to fry's or order online?

EDIT: would this be alright? http://www.bestbuy.com/site/Dynex%26...aste&cp=1&lp=1

also, i'm using a regular ol' corsair fan and a regular ol' cooler master fan (for a push pull setup), i'm fairly sure they're both the same speed...should i buy some new ones?

It depends on your vcore, those temps sound about right for an h50

Adequate, but not great. I'd recommend making the effort to get the Shin Etsu or IC Diamond.

It's better if they match, because even at the same RPMs they can have major differences in CFM and Static Pressure; and SP is more important than CFM for rad fans. If you want to spend the money, Akasa Vipers are a great way to go, otherwise, any good quality fan with a decent SP should work fine (The official H50/70 club thread linked in my sig has a great database of fans). I'd also recommend using a splitter with a molex power connect, so both fans can be run off the same (CPU Fan) header; that way they'll maintain the same speed, and power usage won't be an issue.

ETA: And I should mention one more thing. The waterblocks for the Corsair coolers are machined pretty rough, and not entirely flat. I saw a huge drop in temp when I lapped mine to a near-mirror finish. I also upgraded my fans at the same time, so I can't say for sure how much was new fans and how much was lapping; but I'd guess it to be about 50% either way.

The thermal paste on the H50 is fine, it's Shin Etsu. It's also important you use the exact same fans for push/pull otherwise you wont see any difference between using 1 fan or 2 different fans like you're already doing. What is your vCore at on your i5? With my i5-750 at 4GHz on 1.33 vCore my max load temp is only 70c.

Hey clay, you should make sure you have 2 identical fans pulling fresh air from the back of the case through the radiator. I have 2 Cooler master 70cfms and they do great. As for your temperatures, they pretty much relate directly to your vcore. Make sure when you apply thermal paste on your cpu, do a thin line across the cpu - since quad cores seem to like that more.
