Hi.

Everything below is at stock, no oc other than the XMP.

So I finally decided to get a better cooler than the stock one for my rig and I went for a H60 as it fits nicely in my case and I got it for a bargain.

I am going to do a mild overclock but realise I won't get too much from that cooler.

I tried AIDA last night before and after changing the cooler and I could see something was wrong straight away as the temps approached 95/100 after a few seconds.

Having been playin around I can get my temps down to about 77 after a few minutes of AIDA with FPU so I'm much happier now but I've had to turn the. XMP off on my RAM so I'm currently at 1333.

Can anyone help me with some settings that will help me get say a 4.6ghz oc and keep my RAM at 2400c11?

Thanks a lot.
 
I tested to see if the h60 was secured and it seemed to be fine.

I then tightened up a touch.

Now I'm at 90c in bios and I'm in a right mess.

I assume I've spoilt the paste and now I need to reseat?

Trouble is I have no compound and have no idea where to get any from tomorrow.

COuld I have done something worse?
 
I have done this but the h60 comes pre-applied with paste so that's not an issue.

I've stuck the intel cooler back on with what's left of the paste from the CPU and the intel cooler and it's now idling away at about 51c which is obviously miles better than where it was.

So I can chill out and go to sleep, is an idle temp of 50c with a very poor application of paste to be expected?

This is stock with no XMP.

Thanks.
 
HWmon.

I struggled to get one of the h60 bolts off when I removed it to replace with the intel cooler.

Maybe I overtightened it slightly or something.

Anyway I think I should have maybe made myself a little clearer.

I was more than happy with my non XMP temps but was looking for some way of retaining my ram speed while keeping my temps down.

Although I had thought that I should make sure my h60 was properly tight anyway so don't think I was just blindly following what you said :)

Thanks for your help.

I'm hoping some new paste will put me back to where I was of better.
 
Thanks.

Am I best just leaving the ram at 1333 until I've got a reasonable overclock then worrying about the RAM?

I really wasn't expecting the ram oc to hit my cpu temps so hard!

Thank you.
 
Oh by the way, yes I do really need the 16gb as I use this system for lightroom and photoshop too.

If I have to clock it lower but hopefully tighter then so be it.
 
Thanks.

Today's going to be a long day and I've been dreaming about warped motherboards and crushed cpu pins!

Realistically, if I just stick the h60 back on with the old paste, what sort of temp differences could I expect from a proper application of brand new stuff?

If I can't get any thermal paste today I might be forced to try a refit with the old stuff on.

Also, I'm in Manchester, are there any high street shops sellin decent paste?

Maplin and pc world don't seem to have anything great.

Thanks.
 
Thanks but I did check and out of stock.

Think I will just do my best with what's left over and order some from here when I'm happy everything's back to normal.
 
Thanks again.

The more I think about it, the more I feel like I haven't actually damaged anything but until I get home I'll still have nagging doubts.

I guess I could have warped the board, socket or the bracket but I only tightened by the tiniest of amounts...no idea how checking the h60 was seated properly then tightening a whisker could get me to such a bad situation.

Also, in bios last night I noticed that at 1.218v I was idling at 50c+ @4400mhz.

On the stock cooler with a poor paste application does that seem alarming to you? This was without the XMP loaded.

Cheers.
 
Thanks.

No I'm ultra careful and only went about 1mm past hand tight the first time then maybe the same again the next time with a gentle push to check for give. However it went pear shaped from there and I was throttling in bios after a minute or two. I understand that I probably badly unseated the block when I checked for a good join but I really didn't think things would go that wrong.

It's really hard to get a clear picture in my head of where I'm at with it at the moment as I didn't have to test it all properly last night. I just got it to a reasonable temp with the stock cooler so I could sleep.

All I can say for sure is that idling at 800mhz it's 1.14 ish and about 29c but in bios it ramps to 50c+ At 4400mhz and 1.218 volts on the stock cooler.

Wish I'd run a game or something like that just to check I haven't caused a bad join.
 
I think it could be good to clarify my situation here.

The only overclock I have ever had on was the RAM XMP.

When I turned off the XMP my temps were about 77-81 in AIDA with FPU.

At this point I tried to make sure my cooler was properly seated and that's when things went wrong.

As my case doesn't have access to te underside of the mobo I had to disassemble the pc and because I just wanted to make sure my chip and mobo were ok I quickly slapped the intel cooler on.

My current idle of 29c in windows and 50+ In bios are on the intel cooler at optimised defaults setting in BIOS.
 
Thanks.

Top end of safe? Well for the past month the XMP overclock has had me in the mid 80s touching 90 in lightroom exports.

Here's me thinking 77 was ok! It was after a few minutes by the way.

I use hwmonitor, can't remember previous bios temps and I'm on latest f4
 
Room temp was about 20 last night.

I'll try setting voltage manually to 1.218.

When testing the h60 with the XMP on I had the case closed but last night when I tried again it was open. These were my best temps by miles. Fan is an SP120 high performance and it was definitely at full speed. Incredibly loud and lots of air flow.

Previously I was running the stock case fan and cooler with the XMP overclock but I was also blocking the case with the cages. From now on my drives are going on the floor of the case. I understand why my previous temps were so high now...before last night's brief success and euraka that the XMP was causing the high temps.

Memory is Kingston hyper beast 2400c11 at 1.65v.
 
Things aren't looking great.

BIOS reset and temps are 75 ish in gaming with the stock cooler and touching 92 in lightroom export.

Soon up to 100c with the H60.

I'm starting to think something is seriously wrong now.
 
ok I've gone back to the stock cooler and now things are a lot worse.

Bios takes my CPU towards 100c pretty much straight away. Of course I now have minimal paste but I turned off the instant I was in BIOS.

Surely thermal aste cannot account for this?

I've read you can run without paste.

I think i must have warped my board, any takers?

If I slap a layer of paste on tomorrow and my temps seem semi normal I'm just going to be glad I didn't totally mess this rig up.

Yes it feels solid and connected with the h60 on.

Last night all I did was try to gently move the block and tightened slightly but maybe that has done it.

The board seems fine to me and appears to make a straight line across the heatspreader and the heatspreader itself seems fine.

Underneath the board at the socket it could look slightly bowed but I honestly can't see how that would have been caused.

If the board is bent and requires a thick coating of paste to work, what am I looking at temps wise do you think? Is it going to be liveable with?

Also I've inspected my cpu and mobo pins and they are absolutely fine.

Thanks for your help.
 
Ok well I'll have to hunt down some paste tomorrow.

If that doesn't get me up and running again then I'll have to think about getting a new board one wa or the other...or maybe finding some way to prop it up from underneath.
 
Quick update as waterfox decided to lose my post...

Socket appears to be slightly bowed underneath, exactly as you would expect it to look had the CPU installation stressed it...it's in the same direction of force. I do not believe it is possible to do that by over-tightening the H60.

The board appears absolutely straight.

When I took the heatsink off the stock cooler and lay it on the CPU there is no give whatsoever, it feels perfectly flat and secure. Obviously I realise that if the board is warped and pulling the cooler to one side then that will cause these terrible temps.

I'm going to try the stock heatsink tomorrow placed flat on the heatspreader and weighted down and hold a good fan above it. I firmly believe that if temps are fine this way but not with the cooler installed that I have a warped board.

If thermal paste sorts all this out I will be surprised but I've not given up all hope yet.

Thanks again for your advice.
