It probably is the coolest you'll get it to run without delidding the chip.

My very first 4770K would hit 90c under a Silver Arrow SB-E at stock speeds. I was disgusted with that so I RMA'd it and got another. That was a little better but still not fantastic. It started giving me issues so I RMA'd it directly to Intel and I received my third (and current) CPU. This one has now been delidded and lapped. The temperatures at 4.7GHz with a 1.35 volts don't go over 80c now.

It's a risky procedure, you risk damaging a £200+ component and then you're left with nothing. However, if it works (there are plenty of ways to achieve it, I used the vice + hammer method), you will be amazed at the drops in temperatures.

but how fragile is the chip ? or is it more durable then it looks ?

That doesn't seem quite right... I mean, I know chips aren't created equal, but I have an h100i on a 4770k @ 4.2ghz and the highest temp I saw after 5 hrs of prime95 was 53C. I have two corsair SP120s fans in a push configuration.

Edit: I just remembered, did you put any extra washers under the back plate? On intel systems the brackets are loose on the h80i and h100i, just google search "h100i washer fix". I had to put an extra washer under each peg that attaches to the back plate, otherwise the block would be too loose and slide around.

what prime95 test are you doing ? the prime95 test I am doing is the small FFTs test it puts the cpu under 100% load . the coolest temps I herd of with a i7 4770k non delided stock speed under 100% load prime95 small FFTs is 59c to 61c and for a i7 4770k overclocked is 78c to 80c your chip most be in the 99% tile to have those temps

I typically use blend tests, but it still keeps it at 100% load. However, for your sake, I just did small FFTs for about 15 min and got a high of 48C (@ 4.2ghz). And all this is with the crap stock thermal paste that came with the h100i. Are you sure your block is on there tight?

Edit: I'm using CPUID HWMonitor for the temps, are you using the same program? And if so, are you going by CPU temp, or Core #0 temp? Because that may be where the confusion lies. For CPU my max is 48C and for Core #0 my max is 56C.

my corsair h100i is on tight but the back plate did wiggle a lot and was really loose before I screwed on the water block . I thought there was some thing wrong with the back plate being that loose but I checked online and all the forums I read say the back plate is supposed to be loose . what is the ideal size washers to use and should they be rubber or medal ? and were do I get them from ?

i am using realtemp 3.70 to monitor temps . and I don't see how I can add washers because the pins that come threw the motherboard on the back plate only stick out like a half a mm maybe 1mm

Mine did too whenever I first got it, and it bothered the hell out of me. I luckily had some 3 or 4mm thick rubber washers (that I stole out of my old case's HDD caddies lol) and I stuck them between the motherboard pcb and the screws on the processor side. In fact, on my main rig's page, I have a pic of my bare processor and on the right side you can see where I have the washer under the screw. After I did that the back plate was super tight and didn't budge a millimeter, and the block was a lot more secure. Now, because of my luck, I had some on hand, but my guess would be any hardware store would have them. I would find some rubber ones 3-4mm thick and just wide enough to fit the screw.

Edit: Then in your case you may want to get some thinner ones, or get some with a lot of "give" to them. Just whatever you can do to make it not so loose thumb.gif
